In markets where even a delayed rebroadcast is vanishingly unlikely, online streaming is absolutely thriving. For example, a whole lot of anime hits Crunchyroll and Hulu before the fansub groups ever get a crack at it. These sites and a few others are also expanding into live action Japanese and Korean TV. However, I think this only works when there's very little competition (from broadcasters) for individual shows. The BBC is probably in the worst position possible for an attempt to move to this model due to interplay between company-wide policy and the negotiating power of its international counterparts. Previous agreements with cable companies can't help much either.
