Comcast subscribers will be pleasantly surprised to find HBO and Cinemax available on On Demand Online. HBO apparently wants more exposure, especially online, so you’ll be able to see some of its shows and movies through the On Demand Online service soon.

The bad news is that the trial will include only 5,000 nationwide Comcast customers. The good news is that those users will get the most of HBO and Cinemax, including HD streaming and shows like Entourage and True Blood. What do you say? Ready to watch HBO online?
