AOL and Warner say they’ll launch a new video-on-demand service and make 100 old TV series available online. “Company officials said the shows will be available on demand, meaning computer users who search six new Web-based television channels on AOL.com will be able to choose when they watch the shows and which episodes to view. The companies, both part of media giant Time Warner Inc., will profit by sharing revenue from advertising, including banner ads and four 15-second streaming video ads per 30-minute episode.”
