The iTunes U section of the iTunes Store (iTunes link) has expanded with material from a number of different institutions. Among these is PBS, which has added content from the national network, and local stations such as KQED (San Francisco), WETA (Washington, DC), WGBH (Boston) and WNET (New York). This consists mostly of video snippets for teachers, such as clips on topics like solar eclipses and nanotechnology, but also full-length documentaries, and lesson plans for shows like Ken Burns' The War.
The iTunes Store now also has more material from the American Theatre Wing, the Gilder Lehrman Institute, the Indianapolis Museum of Art, ResearchChannel, and the US Holocaust Memorial Museum. Schools are represented as well, including universities such as American Military, Central Washington, Lehigh, Maine, Southern California and the University of the Pacific. Colleges now include Rock Valley and Wellesley, and prospective lawyers can listen to lectures from the New York Law School. As it is educational, much of the new iTunes content is free.
