Employees of video-sharing site Revver said they breathed a sigh of relief Thursday after management informed them that the company had been acquired by LiveUniverse, a little-known online entertainment network owned by MySpace.com co-founder Brad Greenspan. Representatives from both companies declined to comment, but two Revver employees and an executive at a company that had inquired about bidding on Revver said managers there had informed them the sale was done.
