This is the broadcast schedule for March 18, 1922 (the first day of broadcasting) for radio station WFI, owned by the Strawbridge & Clothier Department Store. The station later merged with WLIT, owned by the Lit Brothers Department Store using the combined calls of WFIL. Back in 1922, the newspapers didn't usually list radio programs. You had to look in the advertisement section of the store that owned the station. This listing was in a Strawbridge & Clothier ad.
