CBS has bought 10-month-old celebrity gossip blog Dotspotter, for a reported pricetag of 10 million. The rumor was first reported on Valleywag. The site is co-founded by CEO Anthony Soohoo. The plan might be to cross-promote with the CBS TV network, as CBS also launched celebrity news site Showbuzz in June and produces two celeb tabloid shows: The Insider and ET. CBS also recently bought financial video blog Wallstrip and social music site Last.fm.
