CBS Is the first broadcaster to offer full-length programs on V CAST, Yahoo! Finance reports. Starting on Tuesday, CBS Mobile will offer both "Late Show with David Letterman" and "The Late Late Show with Craig Ferguson" episodes commercial-free to all V CAST subscribers.

"While we continue to provide short clips of our shows, we're seeing a growing demand for the availability of full length, network quality shows on video on demand mobile video," said Cyriac Roeding, executive vice president of CBS Mobile, in the announcement.

Now that the technology is there, expect to see more full-length episodes available on cellphones. We've never been huge fans of the 2-minute "snack" approach to television on mobile; this is a huge step in the right direction.
