The 10 largest corporate mergers in U.S. history

FBN’s Edward Lawrence discusses Comcast’s $65 billion bid for 21st Century Fox assets.

Merger mania has reached a fever pitch in corporate America as Comcast announced Wednesday a $65 billion all-cash bid to acquire 21st Century Fox assets.

21st Century Fox previously agreed to sell its entertainment assets, including the Twentieth Century Fox film and TV studios along with cable and international TV businesses, to Walt Disney. The deal was for $52.4 billion in stock.

Comcast’s rival bid came one day after a federal judge cleared AT&T’s $85 billion buyout of Time Warner. When completed, the AT&T- Time Warner deal will be the fourth largest in the history of North America.
