Interactive Internet television is popping up across television sets and computer screens across the country. But for those of you who have not caught on to the new sensation, many network Web sites offer an easy guide.

“ABC’s Enhanced TV is a live Interactive Television experience on the Internet that allows you, the TV viewer, to interact with the telecast.”

According to the ABC Web site, the “Enhanced TV experience” provides regular coverage of “Who Wants to Be a Millionaire,” “Sunday Night Football” and “Monday Night Football.” The Web site enhances the television shows by providing in-depth program information, and giving you the chance to interact with the telecast through play-along games, polls and chats.

To “play along” with the television broadcasts, you must be able to see your television set and computer screen at the same time.

The “Millionaire” site also features an online version of the game that can be played at any time, however, like the interactive version, no actual money or prizes can be won.

Other featured ABC Enhanced TV programs include: the “2001 FedEx Orange Bowl,” “The View,” “ABC 2000: The Vote,” “ABC’s Primetime Emmy Awards Show,” “ABC’s Daytime Emmy Awards Show,” “Super Bowl XXXIV,” and the “2000 Nokia Sugar Bowl.”

NBC’s Web site does not offer as much interaction and does not provide a counter part to ABC’s Enhanced TV. The home page includes this weeks featured shows and events and links to local stations and all NBC shows.

The most interactive feature is NBCi Chat, which allows viewers to “chat about ‘Fear Factor,’ ‘SPY TV,’ and all your favorite NBC shows in the NBCi ‘Talk City’ chat rooms.”

The FOX home page is not much different from NBC, however it does offer “FOX Community” where viewers can link up with other fans on message boards, and e-mail FOX. The homepage also offers a link to www.FOXinteractive.com which claims to have games and polls, but only provides advertisements for FOX-related PlayStation games.

Other featured links include local stations, shopping for FOX videos and DVD’s, www.FOXkids.com includes shows, polls and contests just for kids, and www.FOXsports.com features statistics, videos, games and updates.

CBS’s Web site is closely related to NBC and FOX, mainly featuring the week’s line-up of shows, but has even less of a chance to interact with the broadcast. There are no message boards, or chat rooms except for each individual show.

Even the highly anticipated “Big Brother 2,” has only opinion polls, a 3-D virtual tour of the house, and live video streams.
