Michael Edlavitch was a middle school math teacher in Minnesota when he started a website with free math games to engage his students. With free online tools, a passion for math and an initial investment of just $10 to register his domain, www.hoodamath.com was born. Eventually Michael’s website became popular with more than just his students. So Michael gave Google AdSense a try as a way to earn money by placing ads next to his content. As word spread and traffic grew, the revenue generated from his site allowed Michael to devote himself full time to Hooda Math. Today, www.hoodamath.com has more than 350 educational games and has had more than 100 million unique visitors to the site. Beyond building a business for himself, Michael is helping students everywhere learn math while having fun.

Over in New York, Roberto Gil designs and builds children’s furniture—loft beds, bunk beds and entire custom rooms. Casa Kids’ furniture is custom designed for the family to grow along with the child. Roberto works out of his Brooklyn workshop and doesn’t sell to large furniture stores, which means the Casa Kids website is an essential tool for him to connect with potential customers. To grow even further, Roberto began using AdWords in 2010. In the first few months traffic to his site went up 30 percent. Today, two-thirds of his new customers come from Google. Meet Roberto and learn more about how he’s making the web work for Casa Kids:



These are just two examples of how the web is working for American businesses. According to a McKinsey study, small businesses that make use of the web are growing twice as fast as those that aren’t on the web. That’s because the web is where we go for information and inspiration—from math games to practice over the summer to someone to design and build that perfect bunk bed for your kids. Ninety-seven percent of American Internet users look online for local products and services. Whether we’re on our smartphones, tablets or computers, the web helps us find what we’re looking for.

Here at Google, we see firsthand how the web is helping American businesses grow and thrive. Through our search and advertising programs, businesses like Casa Kids find customers, publishers like Hooda Math earn money from their content, and nonprofits solicit donations and volunteers. These tools are how we make money, and they’re how millions of other U.S. businesses do, too.

In 2012, Google's search and advertising tools helped provide $94 billion of economic activity for more than 1.9 million American businesses—advertisers, publishers and nonprofits. This represents a 17 percent increase from 2011. Check out the impact made in each state, along with stories of local businesses using the web to grow.

Whether it’s building skills or building furniture, Google helps to build businesses. We’re thrilled to be part of such a vibrant industry and are committed to continuing to help make the web work for people and businesses everywhere.

Ten years ago we launched AdSense to help publishers earn money by placing relevant ads on their websites. I can still remember the excitement and anticipation as AdSense went live that first day. Our small team huddled together in a cramped conference room, and right away we saw that publishers were as excited about AdSense as we were.

Fast-forward 10 years, and AdSense has become a core part of Google’s advertising business. The AdSense community has grown to include more than 2 million publishers, and last year alone, publishers earned more than $7 billion from AdSense. AdSense is a community that thrives because of all the content creators we are so fortunate to partner with. Their stories inspire us to do our part to make AdSense great.

On this occasion, it’s especially inspiring to hear the stories of partners who have been with us since the very beginning—like a retiree in New Zealand who was able to pursue her dream of writing about her garden, a tech support expert in Colorado who can spend more time with his kids, and a theme park reviewer who now sends employees around the world to test and review rides—all thanks to money earned from AdSense.

As part of our 10th anniversary celebration, we hope you’ll tune into our live Hangout on Air today at 10 a.m. PDT (5 p.m. GMT) on the AdSense Google+ page. I look forward to joining several of our partners to share stories from the early days of AdSense, talk about how we’ve all grown since then, and discuss the future for publishers and online advertising. And if you want even more 10th anniversary celebration, just visit our AdSense 10th anniversary page at any time.

Thanks to modern technology you can connect with your loved ones by sending a quick note, a photo of your cat, even a smile :) around the world in seconds. But one of humanity’s most iconic forms of communication—the kiss—has been left out in the cold. Now, though, you can send a kiss to anyone, anywhere in the world, through Burberry Kisses, a new campaign from Burberry and Google. And not just any kiss, but your kiss.

To get started, simply visit kisses.burberry.com and pucker up in front of your webcam (this works best on Chrome). Using unique kiss-detection technology, the site will detect the outline of your actual lips, which you can choose to dress up with a Burberry lipstick color. If you’re using your touch screen mobile or tablet, you can actually kiss your screen (you might want to wipe it off first) and your lip outline will be taken from there. After that, write a short message and send it to someone from your Google+ friends list or via email. Then sit back and see the envelope with your message fly from your city to the receiver’s destination across a 3D landscape. The receiver gets an email, from which they can see the same journey, read your message and hopefully respond with a kiss of their own.



For an example, see this message I sent to my mom this morning. All the kisses being sent around the world can be seen in a real-time interactive map, capturing the story of the world’s love. You don’t have to kiss and tell: all kisses are private unless you choose to share.

Burberry Kisses is the latest campaign in our Art, Copy & Code project, an ongoing series of brand partnerships to re-imagine how brands tell stories in a connected world. With this project, we’ve tried to create a beautiful experience that comes to life across all screens, and helps connect you to the people who are important to you, wherever they are. For more details on the campaign, see our agency blog or visit our website.

Last year, we started a program to partner with advertisers and agencies to re-imagine how brands tell stories in a connected world. Project Re: Brief set out to recreate some of the advertising industry’s most iconic, classic campaigns using the latest technology tools. This year we’re expanding that program to work with some of today’s most iconic brands and innovative marketers, in our new project: Art, Copy & Code.

Art, Copy & Code is a series of projects and experiments to show how creativity and technology can work hand in hand. Some of these will include familiar brands like Volkswagen, Burberry and adidas—projects developed in partnership with their creative teams and agencies. Others will be creative experiments with innovative filmmakers, creative directors and technologists to explore how brands can connect with consumers through a whole range of digital tools—including ads, mobile apps and social experiences. Our first partner project is a new social driving experience—Volkswagen Smileage.

Building off their 2012 campaign, “It’s not the miles, it’s how you live them,” Volkswagen Smileage is a mobile app and web service that aims to add a little bit of fun to every drive, from your daily commutes to holiday road trips. The app measures the fun factor of each trip using a metric called “smileage,” based on signals like weather, traffic, location, time and social interactions (e.g., a long drive on a sunny Saturday afternoon might accumulate more smileage than a morning commute in the snow). You can use it with any car, not just Volkswagens.

Powered by the new Google+ sign-in, you can choose to share Smileage experience with friends and family. For example, during a road trip, photos and videos taken by you and your co-passengers can be automatically added to a live interactive map. The inspiration for the service came from a recent study showing that every day, 144 million Americans on average spend 52 minutes in a car—76 percent of them alone. We wanted to make that time a more shareable experience. Volkswagen Smileage will be available soon in beta—you can sign up on this webpage for early access.

We’ll have many more experiments to share in the Art, Copy & Code project soon—subscribe for updates at ArtCopyCode.com. We’re committed to investing in technology and tools over the long term to help brands and their agencies succeed not just today, but in a digital future that will look very different.

If you’re planning on attending SXSW, stop by the Google Playground on March 9 to see demos of these experiments, or attend our talk on March 10.

This year’s big game was filled with action—brothers battled on the field and a 34-minute-long power outage nearly turned the tide of the game. With all the excitement on the field, we looked online to see what fans across the U.S. were searching for during the game.

Overall, the top trending searches on Google during the game were:

1. M&M’s
2. Beyonce
3. Baltimore Ravens
4. San Francisco 49ers
5. Colin Kaepernick

Other noteworthy trending searches include those about the power outage, which started trending mid-game and ended up ranking eighth out of the most-searched terms during game time. Searches for Beyonce spiked dramatically during her halftime show. And showing that ads drive consumer interest, searches for Chrysler spiked significantly after their fourth quarter commercial.


The most searched team: The Ravens
As they did in the game, the Ravens narrowly beat out the 49ers as the most searched team during the game on Google. The most searched players of the game were Colin Kaepernick, Joe Flacco, Michael Oher, David Akers and Jacoby Jones—thanks to his 108-yard kickoff return.

The Harbaugh brothers’ on-field battle has been one of the big stories of the game, so it’s no surprise that viewers took to the web to find more information on these coaches. While John Harbaugh took home the trophy, Jim was the most searched brother on Google.

Game day commercials
Lastly, it’s not game day without the commercials. Fans were seeking out commercials online throughout the game, driving searches for big game ads on Google 55 times higher this Sunday than the same time last week. The most searched for commercials on YouTube were ads from M&M’s, Mercedes-Benz, Disney’s “Oz Great and Powerful,” Lincoln, and Audi. Searches for "Gangnam Style" were also trending on YouTube, along with searches for big game performers Alicia Keys and Beyonce.

This year many advertisers turned to YouTube to share game day ads and teaser videos in the weeks leading up to the game. In 2013, big game ads or ad teasers were watched more than 66 million times on YouTube before game day.


Now that you’ve seen all the ads, vote for your favorite one on either the YouTube Ad Blitz channel or ADWEEK.com now through February 11. The winners of the Ad Blitz will be announced on the YouTube homepage on February 16.

Will you be Monday-morning quarterbacking the game or the ads?

From time to time we invite guests to post about items of interest and are pleased to have Linzie Venegas join us today. Linzie is head of sales and marketing for Ideal Shield, a manufacturing company in Detroit, Mich. that specializes in bumper post sleeves. Based in a city forged in tradition and steel, Ideal Shield has seen great success on the web—a story Linzie tells us in this post. -Ed.

When my great-grandparents moved from Mexico to Detroit in 1917, they were looking for a better life. They had no idea that one day their grandson, my father Frank Venegas, would invent a product and start a business that would help transform their adopted hometown. Thanks to my dad’s hard work and a little help from the web, that’s exactly what Ideal Shield has done.

Ideal Shield specializes in manufacturing bumper post sleeves. You may have seen these around—they’re colorful covers that slide over the steel pipes that keep cars from running into buildings. As a young child, my first job at Ideal was to assemble mailers for potential customers. Our mailers were unique—I would place a pack of jelly beans into each envelope. Talk about a great way to get a high “clickthrough rate!” Today, I head sales and marketing for the company, and we’ve taken our family business online with phenomenal results.

We began using Google AdWords in 2004 to help potential customers find our product because many people didn’t know what it was. We were drawn to AdWords because everyone could see our ads—but we only had to pay for the customers who clicked through to our website. We also found that the leads were very qualified and had a higher close rate than leads from other sources. So far this year, for every $1 we've spent on AdWords we’ve gotten back $22. We’ve been able to have great success—without jelly beans!—using Google AdWords.

The energy we’ve put into our online presence has produced tremendous growth for our business; we’ve been able to grow our workforce by 20 percent. We’ve also focused on building our local community of Southwest Detroit. Each year we hire many interns from the local high school, Detroit Cristo Rey, and teach them skills that will last a lifetime. We’ve outfitted the junior and senior classes at Detroit Cristo Rey with Chromebooks so that they’ll have access to the power of the web anywhere, and many teachers there use the free Google Apps for Education suite with their students. This year, we were proud to hear that Detroit Cristo Rey achieved a 100% graduation rate and a 100% college acceptance rate. We also work with the Michigan Minority Business Development Council to teach other small businesses in the community the importance of an online strategy and how the web can help small businesses thrive.

My dad started Ideal with himself, my mother and a couple of laborers; today this family business has more than 35 employees and annual sales of $14 million. With help from the web, his hard work, determination and “out of the box” thinking have made Ideal a symbol of strength and renewal in Southwest Detroit. My father has always told me that if you take care of the community, the community will take care of you. Detroit is our community—it’s our heart, it’s our home. We’ve been surprised and delighted at how much the web has contributed to Ideal Shield, and we’re happy to share that success with Detroit. We can’t wait to do more!

The stats are in, and one clear winner from this year’s summer sports has emerged: digital media. Here’s a quick look behind the “screens” at how the web blew records away around the world, at the most wired Games ever.

Searches set a new pace
Mirroring the growth of the web and digital media, Google search volume around the world was dramatically higher this year than during Beijing in 2008:

• Driven by a 900 percent increase in [ryan lochte] searches, American interest in [swimming] spiked 25 percent higher than 2008 levels.
• The “Fierce Five” vaulted U.S. searches for [gymnastics] to almost double the 2008 peak.
• Spurred on by a record-breaking performance by sprinter Usain Bolt, Jamaican searches for [track and field] raced up 40 percent from 2008.
• Japanese gymnast and first-time gold medalist [kohei uchimura] proved he’s a “superman” in search as well as on the tumbling mat, with search volume in his home country up 420 percent over the last games.
• Success may have been sweeter the second time around for wrestler [sushil kumar], the first Indian athlete to win an individual medal at successive Olympics, with searches up more than 375 percent from the 2008 games.

Here are a few more search snapshots:

Top Athlete Searches (U.S.)	Top Athlete Searches (U.K.)	Top Artist Closing Ceremony Searches (U.S.)
Michael Phelps	Usain Bolt	Jessie J
Ryan Lochte	Jessica Ennis	Beady Eye
Lolo Jones	Michael Phelps	Gary Barlow
Usain Bolt	Victoria Pendleton	Ed Sheeran
Alex Morgan	Andy Murray	Freddie Mercury

Global streaming goes the distance
YouTube powered the live stream for NBC Olympics and for the International Olympic Committee’s YouTube Channel, making the world’s games even more global and accessible. NBC Olympics saw more live streams than during the entire Beijing Games—more than 159 million total video streams and more than 64 million live streams across YouTube's online, mobile and tablet experiences. In all, more than 20 million hours of total video was streamed over 17 days. And of course, the Games were also streamed on the IOC’s channel (youtube.com/olympic), with tens of millions of streams to 64 countries in Asia and Sub-Saharan Africa. We’ll have more details on the YouTube blog soon.

The multi-screen relay
More than ever, people experienced the Games not just via the TV broadcast, but on desktops, mobile phones and tablets. Through research panels conducted in partnership with NBC in the U.S., we learned a bit more about how this played out:

• Mobile makes a strong showing: Many viewers turned to one or more “second screens” beyond TV to keep updated on the Olympics—nearly half of those who did (44 percent) did so via a mobile phone or tablet.
• Power viewers: Second-screen viewing didn’t seem to diminish participants’ interest in watching the games on TV...in fact, it increased it. People who followed the Games on TV plus one other screen watched 52 percent more Olympics on TV than those who didn’t; people who followed on two additional screens spent more than twice as much time (105 percent) with TV. And people who watched live streams of events online watched 66 percent more Olympics on television than people who followed exclusively on TV.
• Synchronized usage: Overall, nearly 56 percent of people who followed the Games on TV and at least one other screen did so simultaneously. These simultaneous viewers also watched TV for 67 percent longer than those who only watched TV.

Gold for digital businesses
Brands who invest in digital marketing to connect with customers grow their own businesses and help make great content possible. A few campaigns that caught our eye:

• Visa’s global “Go World" campaign invited fans to show their support for Team Visa athletes in the form of cheers across social media. The campaign generated more than 59 million cheers, and Visa’s YouTube channel accounted for more than 47 million views of Visa’s commercials and athlete training videos from around the world.
• Insurance provider Zurich launched a successful “Share your Sports Moments” marketing campaign on Google and YouTube, featuring members of the German Olympic team. The result: a significant uplift in the number of leads who then signed insurance contracts.
• Lloyds TSB Bank, presenting partner of the Olympic Torch relay, conducted a successful AdWords campaign that kept pace with the Olympic torch as it passed through towns in the U.K., resulting in more than 190,000 clicks and more than 2 million impressions over three months.

Higher traffic and increased investment in the web also helped online publishers in a big way:

• In the U.S., across 2 million sites in our Google Display Network and the DoubleClick Ad Exchange, ads shown on sports-related websites increased by 19 percent, while revenues (RPMs) for these sites increased by 14 percent, compared to the two previous weeks.
• Our premium ad serving platform for publishers (DoubleClick for Publishers), which helps some of the web’s largest publishers make money from their content, broke a new record, with one major publisher serving more than 400 million ad impressions in a day across its website and mobile content—driving higher revenues and more free content.

A fun note to end on: showing how the web can fuse data and creativity while opening the playing field, one of our software engineers used Google App Engine to create a “per capita” medal tally (the data is real, the accounting is somewhat creative). On this basis, one country stands above all others—congratulations to the most successful nation of the last two weeks, Grenada!

A few months ago, we introduced Project Re: Brief, our experiment to reimagine online advertising. We took some of the most loved ad campaigns from the ‘60s and ‘70s and and brought them back to life for the digital age with the help of the advertising legends that made them in the first place. Together, we created a series of ads designed to start conversations and fire up imaginations about what technology can make possible, such as ads that enable two strangers on opposite sides of the world to connect over a can of soda, or that translate a customer service experience into an instant, shareable, personalized animated video.

But Re: Brief is not just about the ads themselves. It’s also about the creative process behind them: bringing “old school” advertising legends and technologists into the same room to create digital ads that consumers love as much as they loved the iconic campaigns of yesterday. To share this experience, today we premiered the documentary film Project Re: Brief, directed by Emmy winner Doug Pray, at the Cannes Lions International Festival of Creativity—also available on YouTube.

This hour-long documentary follows the story of the five art directors and copywriters who made the original ads as they come out of retirement to “Re: Brief” their classic campaigns: Harvey Gabor (Coca-Cola’s “Hilltop); Amil Gargano (Volvo’s “Drive it like you hate it”); Paula Green (Avis’ “We try harder”); and Howie Cohen and Bob Pasqualina (Alka-Seltzer’s “I can’t believe I ate the whole thing”). While major shifts in technology have reshaped the advertising business, as we learned from our heroes of the past, the basic tenets of storytelling haven’t changed. We found these icons’ ideas, wisdom and passion for great advertising inspiring and hope you do as well.

Today StopBadware is announcing the formation of an industry partnership to combat bad ads. We’re pleased to be a founding member of the Ads Integrity Alliance, along with AOL, Facebook, Twitter and the IAB.

Since its beginnings in 2006, StopBadware has enabled many websites, service providers and software providers to share real-time information in order to warn users and significantly eliminate malware (such as viruses, phishing sites and malicious downloads) on the web. We believe that the Ads Integrity Alliance can make a similarly important contribution to the goal of identifying and removing bad ads from all corners of the web.

In 2011, Google alone disabled more than 130 million ads and 800,000 advertisers that violated our policies on our own and partners’ sites, such as ads that promote counterfeit goods and malware. You can read more about our efforts to review ads and also see the numbers over time. Other players in the industry also have significant initiatives in this area. But when Google or another website shuts down a bad actor, that scammer often simply tries to advertise elsewhere.

No individual business or law enforcement agency can single-handedly eliminate these bad actors from the entire web. As StopBadware has shown, the best way to tackle common problems across a highly interconnected web, and to move the whole web forward, is for the industry to work together, build best practices and systems, and make information sharing simple.

The alliance led by StopBadware will help the industry fight back together against scammers and bad actors. In particular, it will:

• Develop and share definitions, industry policy recommendations and best practices
• Serve as a platform for sharing information about bad actors
• Share relevant trends with policymakers and law enforcement agencies

Bad ads reduce trust in the web and in online advertising. The web puts the world’s information at your fingertips and has given everyone a platform to speak, listen, engage and unite. The growth that businesses generate from online advertising has enabled an enormous part of this platform. We think the web is worth fighting for, which is why we strongly support the Ads Integrity Alliance’s efforts to tackle bad actors who seek to damage it.

Mobile advertising has become a core part of marketers’ and publishers’ digital strategies, helping to fuel business growth and great content.

To make mobile ad buying seamless and accessible for more than a million AdWords advertisers, today we're integrating our AdMob technology directly into our AdWords system. This enables advertisers to run effective campaigns across the more than 300,000 mobile applications running ads by AdMob—all from within the AdWords interface. It also helps AdMob developers and publishers increase their revenue by giving them access to a large number of new advertisers. AdWords advertisers can now manage, measure and adjust search, display and video ads, reaching people on more than 2 million websites and hundreds of thousands of apps, across all screens.

Bringing together the best of AdWords with the best of AdMob is an important step in building integrated solutions that help all businesses get the most out of digital marketing. This complements DoubleClick Digital Marketing, our new unified ad platform for larger marketers and agencies who use DoubleClick’s ad technology, which we announced earlier this week.

As mobile usage continues to explode, businesses increasingly need to adapt their marketing strategies to mobile platforms and mobile-specific consumer trends. For more information about how AdWords is helping marketers “go mobile,” read our post on the Mobile Ads Blog.

We’re in the midst of an online advertising revolution that makes the consumer the center of all we do—with creative tools to make ads that don’t just inform but inspire and dazzle, and measurement frameworks that go beyond clicks to drive real emotional engagement. The next step is to look beyond the ads themselves and reimagine the entire system of buying and selling ads online in a way that puts users first. Today, at our DoubleClick Insights conference, we’re gathering with our closest customers to discuss how we can partner to accomplish this and to unveil some tools for advertisers and publishers that we think will help us all reach this goal.

In particular, we’re introducing DoubleClick Digital Marketing: the first modern ad platform built for the modern digital world. You can read the details on the DoubleClick Advertiser blog, or watch live. This represents the biggest overhaul ever of our DoubleClick ad platform, used by agencies and large advertisers around the globe for digital media buying. One of the central challenges we’re looking to solve with this effort is that digital marketing is still incredibly complex—with marketers juggling multiple systems to manage their different digital efforts across banner ads, paid search campaigns, mobile ads, online video and measurement using systems that don’t talk to one another. We think of this a bit like an old school ‘90’s stereo system, with separate CD, cassette and radio players and a mess of wires in the back. What we want to provide to our partners should be more like the intuitive, powerful smartphones we carry in our pockets today—which not only play all our favorite music, but take pictures, keep our schedules and more.

Towards this end, DoubleClick Digital Marketing will weave together the technologies that buyers currently use to plan, manage, schedule, deliver and measure their online buys in a way we think will not only help them work smarter and faster, but ultimately be more responsive to their customers and deliver better ads.

For our publisher partners, our focus continues to be on bringing together the best of our products, and those of Admeld, the publisher technology company we acquired last year. So we're announcing some new tools to give publishers greater transparency into their businesses and better ways to work with their partners, for example a new Market View on the DoubleClick Ad Exchange that gives them the big picture of what’s happening across the exchange, rather than just their own performance. We think that ultimately, by empowering publishers’ growth and success and enabling them to continue funding great online content, everyone wins.

For more details on our announcements today, be sure to check out our DoubleClick Advertiser and DoubleClick Publisher blogs throughout the week, or tune in to the live stream of DoubleClick Insights, from 9am-1pm PT today, June 5.

This is the second in a series of posts that will provide greater transparency about how we make our ads safer by detecting and removing scam ads. -Ed.
Last month, I shared an overview of the technology Google has built to prevent bad ads from showing on Google and our partner sites, including our efforts to review accounts, sites and ads. To illustrate the scale of this challenge, today I’d like to provide some metrics that give greater insight into the scale of the problem we’re combating.

Bad ads have a disproportionately negative effect on our users; even a single bad ad slipping through our defenses is one too many. That’s why we’re constantly working to improve our systems and utilize new techniques to prevent bad ads from appearing on Google and our partner sites. In fact, billions of ads are submitted every year for a wide variety of products. We have a set of ads policies that cover a huge array of areas in more than 40 different languages. For example, because we aim to show safe, truthful and accurate ads to our users, we don’t allow ads for misleading claims, ad spam or malware.

Ads that are in violation of our ads policies aren’t allowed to be shown on Google and our AdSense partner sites. For many repeat offenders, we ban not just ads but also advertisers who seek to abuse our advertising system to take advantage of people. In the case of ads that are promoting counterfeit goods, we typically ban the advertiser after only one violation. Here are some metrics that give some insight into the scale of the impact we have had over time, showing the numbers of actions we’ve taken against advertiser accounts, sites and ads. You can see that the numbers are growing—and growing faster over time.

Year	Advertiser Accounts Suspended for Terms of Service and Advertising Policies	Sites Rejected for Site Policy	Ads Disapproved
2011	824K	610K	134M
2010	248K	398K	56.7M
2009	68.5K	305K	42.5M
2008	18.1K	167K	25.3M

We find that there are relatively few malicious players, who make multiple attempts to bypass our defenses to defraud users. As we get better and faster at catching these advertisers, they redouble their efforts and create more accounts at an even faster rate.

Even in this ever-escalating arms race, our efforts are working. One method we use to test the success of our efforts is to ask human raters to tell us how we’re doing. These human raters review a set of sites that are advertised on Google. We use a large set of sites in order to get an accurate statistical reading of our efforts. We also weight the sites in our statistical sample based on the number of times a particular site was displayed so that if a particular site is shown more often, it’s more likely to be in our sample set. By using human raters, we can calibrate our automated systems and ensure that we’re improving our efforts over time. In 2011, we reduced the percentage of bad ads by more than 50 percent compared with 2010. That means the proportion of bad ads that are showing on Google was halved in just a year.

Google’s long-term success is based on people trusting our products. We want to make sure that the ads on Google are safe and trustworthy, and we’re not satisfied until we do.
