Its official: Confirming the leaks from last night, Comcast has announced it will acquire Time Warner Cable. This combination of the countrys #1 and #2 cable companies will stretch from coast to coast, as TWC controls markets like New York City and LA, while Comcast strongholds include Philadelphia and Washington DC. TV isnt the only medium in play either, since as Gigaom points out, the two companies together account for about 33 million internet customers as well.
