Time Warner doesn't necessarily have any reason to launch an HBO app for the iPad or any other device, company CEO Jeff Bewkes said when discussing the company's latest financial results. The media firm could "easily" make an app to stream the cable channel's shows to Apple's tablet but doesn't have any motivation to do so. Since it goes over the web, the online HBO Go service doesn't have to be tied to a particular platform and gives Time Warner control over how the service works for any device, not just the iPad.
