WPST

WPST, virtual channel 9 (UHF digital channel 51), is an ABC-affiliated television station licensed to Possum Springs, Pennsylvania. It has been owned by the Hearst Television subsidiary of the Hearst Corporation since the station's inception, making this one of a few stations that have been built and signed on by Hearst. On cable, WPST is carried on Comcast Xfinity channels 8 (channel 6 in Fort Lucenne, and channel 4 in some outlying areas) (standard definition) and 804 (high definition), and Verizon FiOS channels 4 (SD) and 504 (HD).

Digital channels
The station's digital channel is multiplexed: On August 3, 2009, WPST converted its traffic/weather subchannel into a This TV affiliate.

Until January 2014, WPST was one of a handful of ABC-affiliated stations and one of a few Hearst-owned ABC affiliates that broadcast their HDTV signals in 1080i rather than the 720p format of most other ABC stations. WPST announced that will convert to the 1080i format in January 2014.

On January 1, 2018, WPST replaced This on WPST-DT2 with Cozi TV upon the end of Hearst's carriage agreement with parent Tribune Broadcasting for that network.

Analog-to-digital conversion
WPST shut down its analog signal, over VHF channel 4, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcasts on its pre-transition UHF channel 51. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 9.
