NetRadio is a leading broadcaster of originally programmed audio entertainment over the Internet through their Web site, www.netradio.com. They organize their music and information content into highly targeted audio channels grouped as communities of similar interest or "COSIs." They attract customers using audio content, rather than relying solely upon a text-based site, to extend the time visitors spend at NetRadio, thereby creating a "sticky" Web site. I/PRO, Internet Profiles Corporation, an independent consultant that monitors Web site traffic, has estimated that in September 1999 1,058,237 different users, each of whom was counted only once, listened to one or more of their 120 music and news audio channels. I/PRO has also estimated that in September 1999 the average time a visitor spent listening to any of their audio channels was approximately 29 minutes. On October 12, 1999 they launched their redesigned Web site that reflects their new logo, revamped look and enhanced functionality.
