In an effort to keep interest high, FOX has begun to release downloadable versions of its prime time hits. Using Fox's "Full Throttle" player, visitors to FOX.com can download episodes of Prison Break and other FOX hits free with only mild advertising. The service, like other networks offerings, will eventually segue into a pay-per-download service by the end of the year. Shows such as Prison Break, Bones, and Vanished as well as other shows will be made available throughout at least October and November.
