CNN is set to buy Mashable, a social media blog, for around $200 million, says Reuters blogger Felix Salmon, who’s attending the SWSX in Austin Texas. He says CNN could announce the deal as early as Tuesday. Separately, the New York Times confirmed talks are ongoing but that the deal is far from over. Peter Cashmore, who started the blog in 2005, reportedly denied the deal to his senior editors Tuesday evening Manila time. If it does happen, it would be a major coup for Cashmore and would strengthen CNN’s reach and presence in the blogging space.
