This seems reasonable. However I seem to remember that the actual listings in the UK are 'owned' by some central authority (I forget who but it's got something to do with the Radio Times) and you license the right to publish them. While it's a fact that a show is on it's also content owned by some authority. This is where lawyers make their money.
