Comcast is set to acquire Time Warner Cable and become the nation's biggest cable TV provider.  

Word of the massive, all-stock deal worth more than $44 billion first came down on Wednesday.  

The deal amounts to $158.82 per share, which is about 17 percent above the Wednesday closing price of Time Warner Cable Inc. shares. 

The deal trumps a proposal by Charter Communications Inc. to buy Time Warner for about $38 billion in cash and stock worth $132.50 per share and comes just a day after Charter said it was preparing a proxy fight by nominating a full slate of directors to Time Warner Cable's board. 

The merger of the two largest cable companies is likely to bring scrutiny by regulators over antitrust rules.
