ExerciseTV is a free video-on-demand (VOD) television service, available to digital cable subscribers in almost 35 million homes across the United States (and growing).
Game on Demand (also called GoD) is to computer games as video on demand is to video rental or video purchase.
All Netflix plans also include access to the site's video-on-demand service, so you can watch movies and TV shows on your computer while you're waiting for your next discs to arrive in the mail.
If you're in the US, head to Amazon, visit the Video on Demand section and search for Coronation Street.
If you don't own all the episodes of Smallville yet, today many full episodes can be viewed online at no charge and others can be viewed as Video on Demand for a small price.
