Arianna Huffington, the co-founder and chief editor of the Huffington Post, says a deal that let AOL buy her online newspaper was signed at the Super Bowl.

Things moved very quickly. A term sheet was produced, due diligence began, and on Super Bowl Sunday the deal was signed, Huffington said in a post on the newspaper's website.

It was my first Super Bowl - an incredibly exciting backdrop that mirrored my excitement about the merger and the future ahead, she said.

She said AOL CEO Tim Armstrong proposed the deal in early January.

On Sunday, AOL Inc. announced it entered into a deal to buy the Huffington Post for $315 million, approximately $300 million of which will be paid in cash and the rest is in stock.
