NBC is upping the online ante by adding a raft of new series to their online free streaming, full episode service. Joining The Office and other pre-existing programs will be new shows such as The Black Donnellys, Medium, Friday Night Lights and, most importantly, Heroes. Not sure if it’s going to be all episodes for every series, but Heroes at least will be available from the pilot on.

Watching TV shows on their coporate overlords’ websites is always a mixed bag. You have to watch them in your browser, and the commercials are often annoyingly repetative, but it’s a nice option for shows you’ve missed or just something to do on your lunch break as you ponder the true nature of Sylar.
