AOL has announced that its entire original video content library will be distributed and monetised on YouTube.

The deal brings nearly 20,000 high-quality videos from leading AOL brands, including The Huffington Post, TechCrunch and Moviefone, to YouTube's audience.

The announcement was made at Advertising Week 2012 taking place in New York.

With a series of key acquisitions in the online video space in recent years, AOL has become one of the dominant forces in the industry. In April, the company launched The AOL On Network, a platform of AOL's complete video offerings and a curated video hub for consumers that offers premium, short-form video across 14 content channels.

"The AOL brand includes an incredible array of premium video content from some of the most highly-trafficked sites on the web, and this deal provides us with a way to expose that content to a vast new audience," said Ran Harnevo, SVP of Video, AOL.

"AOL and YouTube are two of the biggest names in online video today, which makes this deal an important milestone, not just for us, but for the industry as a whole."

The videos will be curated into 22 channels on YouTube.com, including TechCrunch, HuffPost Live, Moviefone, AOL On Style and AOL On Home. Ad sales will be handled by AOL's sales team, opening up a new revenue stream for the company and delivering a significant amount of brand-safe inventory for advertisers.
