Last month, four million people tapped into Yidio, which has arguably become the Web’s best, yet still under-the-radar, destination for discovering, sharing and viewing television shows and movies. The reason: In less than 18 months, Yidio’s intuitive episode guides, social network and discovery engine have organized the vast mix of television shows and movies on the web, making it quick and easy to watch TV online.

Yidio’s Founders Brandon and Adam Eatros have selected the 2009 NewTeeVee Live Conference happening at the Mission Bay Conference Center as an unveiling of sorts for a site that’s been quietly proving it knows how to manage and capitalize on online television viewing to the benefit of advertisers and consumers alike. At the NewTeeVee conference, the Eatros brothers will share not only the latest version of their site but also news of a private equity investment from a group led by serial entrepreneur Alan Warms and including James Crouthamel, founder of Performics.

At the heart of Yidio’s success is the site’s ability to solve two major problems faced by consumers. First, the marketplace for online TV and movies is unorganized and fragmented across hundreds of content providers. And second, with more and more premium content moving online, knowing when and where your favorite TV shows are located is nearly impossible. Yidio overcomes both hurdles by providing users a personalized entertainment center, online. It’s a place where anyone can easily interact with Yidio’s technology and other users to discover new content.
