At the Macworld 2008 keynote, Steve Jobs, who was Apple's CEO at the time, announced iTunes movie rentals.[26] Movies are available for rent in the iTunes Store on the same day they are released on DVD,[27] though the iTunes Store also offers for rental some movies that are still in theaters. Movie rentals are only viewable for 24 hours (in the US) or 48 hours (in other countries) after users begin viewing them. The iTunes Store also offers one low-priced movie rental a week: in the United States, this rental costs 99 cents. Movie rentals are still not available in all countries but they are available in many countries including the United States, Mexico, the United Kingdom, Canada, Australia, India and New Zealand.[28]There is a weekly promotion in which one to three songs are available to download for free to logged-in users. Free downloads are available on Tuesdays, and remain free until the following Tuesday, when the store gets refreshed with new content.[29] Some artists choose to have select songs available for no charge. This is not available at all iTunes Stores. Some iTunes television programs have begun the same technique to encourage brand loyalty, although those stay longer. In fact, the iTunes Store has a "Free TV Episodes" page where free episodes are organized by length, either as "featurettes" (shorter than 15 minutes) or full-length episodes (longer than 15 minutes). Free content can vary from a preview of a show to bonus content to pilot episodes and entire seasons of TV shows (examples of free seasons include HBO's The Weight of the Nation and ABC's Pan-Am). Some networks, such as ABC and NBC, have their own pages of "Free Season Premieres".
