Google has been in talks to acquire video search startup Baarzo, according to sources with knowledge of the company. However, those sources were less clear about whether the companies had reached a final agreement. (One suggested that the deal had closed, the other was noncommittal. A third source had also said that Baarzo has been acquired.) The companies both declined to comment, Google offering its standard note: “We don’t comment on rumors or speculation.” Baarzo describes its product as “true video search,” allowing users find specific moments in a video, like a slam dunk in a basketball clip. If it delivers on that promise (I can’t say one way or another, since the company is not accepting signups), that would be pretty appealing to Google, both for search in YouTube and for the company’s efforts to offer “universal” search across media types.
