Confusing the question of which television shows will remain on Apple's iTunes Store and which will not, Apple said Monday that new episodes of the Fox TV show House will not be available this fall. It's not that Fox is joining NBC in yanking its programs from the online Apple store; it's that House is produced by Universal Media Studios, a subsidiary of NBC Universal. The announcement came just one week after two of NBC's new shows made their online debut on the iTunes Store last week. One of them, Chuck, is produced by Warner Bros; the other, Journeyman, is produced by 20th Century Fox.
