24/7 has big money behind it, at least not on the level of Yahoo and Fox. However, I'm not sure how much money Yahoo is willing to put into Rivals. Certainly the BDJ merger negotiations would seem to indicate they don't have money to throw around. Anyway, at this point 247 has survived the initial year, and is expanding. They've managed to start up in an era where everything computer-related is cheaper, and I don't see them weighing themselves down with as much national/regional staff as the other networks have/once had. They also seem to have all the angles covered: technology, database, and as far as State goes, high quality coverage.
Now, they could do like Rivals and let their technology linger without updates for years on end, but I'll be surprised if they do. They're trending upwards, and I don't think that's a short term thing.
