prompts on a train

My last post has made me think about something we should do for itv. Why don't we do a deal with SouthWest trains so that every commuter service out of Waterloo features a little 30 second announcement on what the best thing to watch on ITV that evening is. The guard would have to read it out probably but they can make it clear that ITV are paying for this to help subsidise train fares (as passengers we have to put up with enough announcements as it is so one more won't make any difference and as it could change every day might be quite welcome for bored commuters). What ITV get out of it is a last minute prompt reaching several thousand potential viewers, nearly all of whom are going home and many of which are probably light viewers. It would have to be executed in a way that doesn't irritate passengers and genuinely adds value but this is probably just an executional twist. Must look into this idea a bit more.
