WPDT

WPDT, virtual channel 4 (UHF digital channel 35), is an NBC owned-and-operated television station licensed to Hobucken, Indiana and serves the Waterbury-Schiller Park-Grand Acres-Hobucken television market.

History
WGAH-TV signed on February 13, 1953 as the second television station in the Waterbury-Schiller Park-Grand Acres-Hobucken television market, 4 years and 8 months after Dumont/CBS station WBIL-TV. It was originially owned by Johnson Broadcasting Ltd. WBIL-TV carried a secondary NBC affiliaton prior to the station's sign on. It has been a full-time NBC station ever since their inaugural sign on.

In 1955, NBC's parent company, RCA, purchased the station, and changed the call letters to WHI. In 1960, the station was once again sold to Plains Television.

On April 8, 1978, Plains Television sold the station to Paramount Television, and changed their name to WPDT. Despite the ownership change, the station stuck with NBC.

On May 24, 1986, following NBC's national rebrand, the station rebranded as "Paramount 4". The name was a mix of the station's owner, and their old analog channel number. This made WPDT one of the few stations in the United States to not have the station's call sign or network affiliation in their branding. The Paramount 4 era is still fondly remembered by people who grew up watching the station.

In 1990, the station went back to the traditional call sign and channel number branding, putting an end to the "Paramount 4" branding.

In 1995, following the launch of UPN, Paramount either had the choice of switching WPDT to said network and leave the upstart WGFC to affiliate with NBC, or sell WPDT and have WGFC join UPN. they chose the latter, and WPDT became an NBC O&O. despite the ownership change, WPDT kept their call letters.

On June 12, 2009, the station signed off its analog transmitter for good, and moved to UHF digital 28. On April 9, 2018, the station moved to UHF digital 36, and again to UHF digital 35 on August 1, 2019.
