In the wake of the sign-off of WKBS-TV in Philly, the city was reduced to two commercial UHF stations for two years before the sign-on of WGBS-TV, "Philly 57." Formerly the signal was used as an outlet for local cable premium channel PRISM until the license was purchased by the Grant Broadcasting System and relaunched with much fanfare as the city's newest entertainment station. Although it didn't market itself as the successor to Channel 48, it unofficially took up the old station's mantle. The station has gone through several ownership changes since its launch; today it is owned and operated by CBS/Viacom as a CW affiliate.
Here are several clips, commercials, and promos from the station's first few years of operation. For more detailed information on the station, click here. Enjoy!
