Google announced a number of partnerships on Monday in an effort to expand its Google Video service, adding music videos from two major record labels through an ad-supported model.

The search giant said it is partnering with Warner Music Group Corp. and Sony BMG Music Entertainment to make the music video collections of both companies available for online streaming at no costs to users.

We see this agreement as an important part of our overall strategy to innovate, find new ways for our artists to connect with their fans, and develop new revenue streams, said Thomas Hesse, President of Global Digital Business for Sony BMG.

Google advertisers will sponsor the videos of both media firms, making the content free for end-users. Select videos from Warner Music will immediately be available for purchase as downloads on Google Video for $1.99.

Advertiser revenue will be shared between Google and the media firms. Videos from both firms will be available starting this month, Google said.
