Reports are coming out of SXSW that Mashable, the widely read website dedicated to all things social media, is in talks to be acquired by CNN for a hefty $200 million. The news was broken last night by Felix Salmon of Reuters, but this morning Pete Cashmore, Mashable's founder and CEO sent out an email to staff denying that a deal had been made.

The site, founded in 2005, has about 20 million monthly visitors and already has a content-sharing agreement with CNN. At $200 million, the purchase, if it goes forward, would be the largest in CNN's history.

We'll have more on the future of Mashable and CNN as the story develops.
