It’s stange that a former corporate cousin of HBO — Time Warner Cable — remains the biggest pay TV company that still doesn’t offer subscribers the opportunity to access the HBO Go digital streaming service. But that will change “soon,” Time Warner Cable COO Robert Marcus tells Bloomberg. Marcus declined to say what’s holding things up — and we’ve been hearing for months that a deal was just around the corner. Still, if Marcus’ prediction is correct, then it means the HBO customers among TWC’s 12.1M subscribers will be able to watch shows such as Boardwalk Empire, Hung, Bored To Death, and Real Time With Bill Maher on demand from Web-connected devices including tablets and mobile phones. It’s important to HBO because TWC serves two of its biggest markets, Manhattan and Los Angeles. TWC and Cablevision are the only major cable, satellite, and telco video providers that still don’t offer HBO Go.
