PBS said Tuesday that it had added programming to the iTunes Music Store, including documentary, primetime and children's programming. As with other videos on the market-leading download service, downloads would cost $1.99 USD. Included in the offering are "Antiques Roadshow," "Nova," "Now," "Scientific American Frontiers," and children's shows "Arthur, "Cyberchase" and "Fetch."

The success of PBS podcasts on iTunes spurred the network to add its programming to the service, which now includes over 220 shows from more than 40 networks. The viewer-supported network would also attach content to each episode that would underscore the benefits of becoming a member of a local PBS station, it said.
