Local cable operators may provide coverage of high school sports，delayed broadcasts of collegiate sports，and call-in shows on public access channels. College and high school football and basketball sometimes are shown at different times during the week on tape.
Pay-Per-View is a subscription service available through cable franchises. Cable sub-scribers can order special events－sports，movies，etc.－by telephone or through the cable converter box. The viewer pays separately for each event，just as in purchasing a ticket. Everything from college sports events to major prizefights is offered on a pay-per-view basis.
Stations on the AM band（535 to 1，605 kilocycles）depend on talk shows and enter-tainment for programming because music has gravitated to FM stations（88 to 108 megacycles），which produce static-free transmission. Consequently，local commen–tray and call-in shows are popular fare on AM radio. Local stations in some cities have adopted all-sports formats，but round-the-clock sports radio has been largely un-successful.
