Todd VanDerWerff says it doesn't make economic sense:
The problem HBO (and the other premium cable channels) faces is that it’s boxed in by its need to be in bed with cable companies. The easiest solution to the problem posed in the Oatmeal cartoon is simply to make HBO Go available to anyone who wants it, for a monthly fee that would probably be slightly larger than what the monthly fee for the TV network is (to offset any costs lost from cable providers). The problem is that if the network does this, it will be seen as declaring war on the very providers who keep it coming into people’s homes. Even though it seems, to a generation raised on the Internet, like everybody watches stuff on the Internet all of the time, the vast majority of Americans still consume their entertainment on TV. Without the cable companies beaming HBO into those people’s homes, the network loses subscriber fees, which robs it of the ability to program anything beyond cheap movies.
Alyssa nods.
