Apple said Monday that it will issue credits to all of its iTunes Store customers who purchased subscriptions to an entire season of a TV series but who discovered that the season was shortened due to the writers' strike. Each "season pass" purchaser, Apple said, will receive vouchers that can be used to purchase any two TV episodes, music videos, or short films. In addition, customers will receive a partial refund for shows that wind up the season with fewer episodes than originally promised.
