So far, there has been no big hit Internet show that defines the medium, in the way that Milton Berle's show did in television's infancy.

Most of the made-for-the-Web shows now online are in short "Webisodes," only a few minutes long, and many are cartoons.

Warner Bros. Online and Brilliant Digital Entertainment have teamed up to create a multipath interactive adventure called The Menace of Metallo. . . . "It's hearkening back to the early days of movies," said Warner Bros. Online president Jim Moloshok. "It's the old cliffhanger episode. You come back next week, you see the next web-isode."

The Computer Network and Intel Corporation today announced they will launch a jointly developed Web site called Mediadome(SM) at www.mediadome.com. From top musical artists to major motion pictures to comic book heroes, Mediadome will merge today's hottest media properties with cutting-edge technology to create a brand new experience in Web-based entertainment. The site debuts on December 31 with a live Webcast of Bill Graham Presents San Francisco New Year's Eve, and will feature an exclusive new program, or "Webisode" every two weeks.
