Netflix has emerged as one of the biggest foes of Comcast’s proposed merger with Time Warner Cable. Despite a recent agreement in which the digital programmer agreed to pay the cable and broadband giant for a direct connection to its 20 million high-speed Internet customers to improve the speeds and quality of its video streams, the two companies are publicly trading shots at each other. On Monday, Netflix said it was opposed to Comcast acquiring Time Warner Cable, a deal that would give Comcast an estimated 40% share of the U.S. broadband market.
