The removal coincides with the expiry of NBC's agreement, which the company decided to let slip due to unhappiness with Apple's pricing policies. While NBC wanted to experiment with different schemes, such as bundles or a test pricing of $2.99 for a single show, Apple refused, insisting that it conform with the standard season pass/$1.99-per-episode format. NBC has launched its own competition through a joint venture, Hulu, but a number of major networks remain on iTunes, including ABC, CBS, Fox and Comedy Central.
