The 1993 Consumer Electronics Show featured demonstrations of the Radio Broadcast Data System. The RBDS System transmits several types of data including call letters of the station tuned to, the station’s current program format, select alternate frequencies for translators or other stations carrying the same program, emergency alerts, traffic bulletins, paging information, and business and navigation information. RBDS also has the potential to deliver advertising and other messages to home, car and portable radios. The receivers are expected to be on the market by mid-1993. (Las Vegas Review-Journal)
