Between the deals to combine Comcast with Time Warner Cable and AT&T with DirecTV, the market for subscriber television in the United States is on the cusp of changing dramatically. According to data from research firm SNL Kagan and reported by cable trade group NCTA, a post-merger Comcast would have some 34 million video sign-ups while DirecTV and AT&T's U-verse together would account for 25.5 million.

Together, the two companies would hold well over half of the market for subscription television in the United States, a landscape mirrored by AT&T and Verizon in wireless.
