AlwaysOn is excited to announce the 2011 OnMedia 100 Top Private Companies list of leading digital media companies operating in the advertising, marketing, and content publishing sectors. While compiling the OnMedia 100 and interviewing the top CEOs, our editors were amazed by how big and even profitable many of these startups had become, which appeared to be a sign that the market was beginning to mature. But just when you start to believe that Madison Avenue has finally figured out how to play the digital game, you learn that the advertising spend compared to where the eyeballs are going is still severely out of whack.

As an example, in the U.S., the average person spends 28% of his or her time consuming media over the Internet, yet Madison Avenue still only spends 13% of its ad dollars on Internet advertising. As Mary Meeker pointed out in her last major Morgan Stanley Internet presentation (Ms. Meeker recently joined VC-powerhouse Kleiner Perkins Caufield & Byers), closing this advertising gap represents a "$50 billion global opportunity."
"The make-up of the OnMedia 100 presents a poetic picture of the mega-trends AO's editors see driving the transformation of digital media and entertainment, namely the explosive growth in smartphones, social networking and social commerce, as well as the globalization of entrepreneurship," says Tony Perkins, founder and editor of AlwaysOn."We also uncovered a new trend that's creating high-growth company opportunity-the emergence of Web analytics as a powerful tool to help advertisers ascertain the 'wisdom of the crowd' and better target their marketing and branding pitches."

The AlwaysOn editorial team would like thank our partners at SAP, the Blackstone Group, KPMG, Silicon Valley Bank, SNR Denton, SecondMarket, and Bridge Bank, as well as industry experts across the globe who helped us scour the entrepreneurial community to identify the top 100 private digital media companies. The OnMedia 100 winners were selected from more than a thousand U.S. and international technology companies nominated by investors, bankers, journalists, and digital media industry insiders.

There are many incredible companies emerging in the digital media space which arguably should have made the list, and we appreciate there will be folks who, with good reason, will be disappointed that their company did not make the list. Given that private company financial and other key metric information is largely not disclosed, and it would be nearly impossible for us to have identified every great OnMedia company on the planet, we consider the OnMedia 100 as a "solid representative list" of the many great companies in the global marketplace. Our congratulations to the winners and the other great OnMedia companies we look forward to covering in 2011!

Tony Perkins is the founder and editor of AlwaysOn.
