Maybe something like reddit, but presented through things like Google TV and Apple TV. If someone can morph social media viewing/browsing into something that emulates channel surfing, then that idea will easily be worth 100's of millions.
EDIT IDEA: If Oprah doesn't have someone doing the following for her, then some group with the right CV items should hop on it! Start finding or putting key moments from shows followed by middle aged-women up on YouTube. (Oprah will make up a lot of this content.) At the same time, launch a social media site tailored for middle-aged women and create APIs so that it can be integrated with TV convergence devices.
Not only will Oprah make more money on her own content this way, she will become the middlewoman for a big chunk of the other content aimed at this demographic.
