THESE DAYS, HAVING A PLAIN old Web site is not enough. Companies are now creating TV- and radio-like "networks" on the Internet a la JamTV Music Network. Run by Digital Interactive Networks and scheduled for a March launch, JamTV aims to be a music megasite. It will include information on some 1,500 alternative-rock recording artists, along with music reviews, video and audio clips--even a store where you can purchase concert memorabilia.

The Web site, www.jamtv.com, plans to broadcast more than 1,500 live concerts this year put on by JamTV partner and concert promoter Jam Productions. One novel feature is the JamCam, which lets viewers position a virtual camera with their mouse to zoom in on, say, Silverchair's drummer Ben Gillies during a live performance. Because video on the Net is still primitive, JamTV plans to distribute CD-ROMs containing video clips of concerts, interviews, and music videos that will supplement the JamTV Web site. The CDs, which will be given away at concerts, will also include software, such as Macromedia Inc.'s Shockwave, for viewing multimedia clips. JamTV also has signed up 350 affiliate radio stations that will link their Web sites to the JamTV site. The radio stations will also promote JamTV's live events on the air. So don't fret if all the U2 tickets get snapped up this spring; you might catch them on the Net instead.
