Microsoft has bought video discovery service Videosurf to “evolve search and discovery of entertainment content” on Xbox 360.

The press release sent out by Microsoft this morning in the US confirms the company will be integrated into Xbox 360 “ecosystem” in some form, noting that it’ll “evolve search and discovery of entertainment content” via Xbox Live.

“This holiday we will launch voice search across our entertainment partners on Xbox Live. Over time, as we integrate VideoSurf’s technology into our system, we are excited about the potential to have content tagged in real time to increase the speed and relevance of the search results,” said Xbox Live director, Alex Garden.

“We are incredibly excited to be working together on our mutual passion for creating amazing consumer experiences and reinventing how consumers search, discover and enjoy content on their televisions,” added Videosurf CEO, Lior Delgo.

Terms of the deal weren’t announced, but TechCrunch reckons as much as $100 million was involved.
