If you’re frustrated that HBO doesn’t make Game of Thrones and other hit shows available to watch on the web shortly after they air, then you might have Time Warner Cable to thank. Unnamed sources tell Bloomberg that Time Warner Cable “and other pay-TV operators are offering incentives to media companies that agree to withhold content from Web-based entertainment services” that “can take the form of higher payments or… threats to drop programming.” Bloomberg says that such incentives are part of Time Warner Cable’s efforts “to keep customers by ensuring access to exclusive content while fending off competition from upstart Web providers.”
