Apple may have two studios lined up for its proposed iTunes TV subscription plan ahead of a winter tablet lanch, sources claim Monday night. Where before the rumored service had merely been proposed to studios, anonymous tips now suggest that CBS and Disney are at least "considering" signing onboard. Under the plan, at least some TV shows across participating networks would be available through a monthly subscription, including CBS and its sibling CW network as well as ABC, ABC Family and the Disney Channel.
