WHYY-TV, virtual and VHF digital channel 12, is a Public Broadcasting Service (PBS) member television station serving Philadelphia, Pennsylvania, United States that is licensed to Wilmington, Delaware. Owned by WHYY, Inc., it is sister to National Public Radio (NPR) member station WHYY-FM (90.9). The two stations share studios on Independence Mall in Center City Philadelphia and transmitter facilities in the Roxborough section of Philadelphia; WHYY-TV also operates a secondary studio in Wilmington. WHYY-TV is one of three PBS member stations serving the Philadelphia market, alongside Allentown-based WLVT-TV (channel 39) and NJTV (channels 23 and 52).
WHYY-TV operates a full-time satellite station, WDPB (virtual channel 64, UHF digital channel 44) in Seaford, Delaware, which serves the Delmarva Peninsula region. WDPB's transmitter is located on Virginia Avenue in Seaford. It is the other PBS member station serving the Salisbury, Maryland market, alongside MPT (channel 28).
In Daniel Walterbury's imagination, WHYY's satellite station, WDPB (serving Seaford and Dover), shares the same branding as WHYY, but WDPB's branding says "WDPB" instead of "WHYY".
