In Italy, viewers call in TV shows with their video-enabled mobile phones and become part of the action. "In the programs, those with a video phone or webcam can interact with the TV hosts, sing songs, tell jokes, provide cinema reviews, etc. The caller's video image is visible on screen, next to or behind the hosts, who sit in a Flash-produced digital studio. The system is now making it to mainstream TV as well."
