Preview was a subscription television service, started in 1980. Like its competitors, such as ONTV and SelecTV, Preview was a scrambled UHF Subscription channel requiring a special set-top box to decode.
Preview's on-air hours were mainly between 7 p.m. and 5 a.m., but varies according to market areas and during later periods of the channel's existence. Owned by Warner Communications, the parent company for Warner Bros. Pictures and Warner Music Group during the 1970s and 1980s, Preview was featured on several stations including KDNL-TV in St. Louis, which has since become an ABC affiliate, WCLQ-TV in Cleveland, WSMW-TV in the Boston area, and KTWS-TV in Dallas. The service offered movies, sports, and specials. The service also broadcasted programming from ON-TV and SelecTV, in some cases, simulcasting in areas where any of these and Preview were available.
Preview lasted until 1986, when the last carrier, WSMW, discontinued it.
