BBC will text you a reminder to watch Phelps win again

The BBC has introduced a clever system to help boost its Olympics ratings. It seems (potential) viewers can sign up to get a couple of text messages a day reminding them that a certain event is about to be shown on TV (such as Phelps going for another gold medal). You could see this idea being applied to a whole range of things. For example radio stations could text you to tune in when a certain song is about to be played. Equally, your favorite sports team could send you a text message when they score and provide information on where you can watch or listen to the game. Businesses could text you when a certain item goes on sale. The list is really quite endless and I wonder if there isn't a business here for someone to create a site called 'Reach Me'. On the site you would sign up for things that you would like to get messages about. I'd suggest that this site go beyond text messages and use a range of other ways to get hold of you. As I say the list could be anything from sports news to product availability. There are some technologies that touch on this space from people like Varolii but they seem to focus more on the company selling than the person who is receiving or buying.
