compete against WIP, CBS began phasing out the sports talk shows in the summer of 1996. Finally, on August 23, 1210 AM went all-talk once again as WPTS (We're Philadelphia's Talk Station). The call sign was changed again less than a month later to the current WPHT to avoid confusion with nearby Trenton, New Jersey's WPST. Ironically, only a year later, WIP became a sister station to WPHT when CBS merged with its owner, Infinity Broadcasting Corporation (at the time part of Viacom). Entercom ownership On February 2, 2017, CBS Radio announced it would merge with Entercom. The merger was approved on November 9, 2017, and was consummated on the 17th. In 2020, WPHT host Ken Matthews was named one of the 100 most important talk radio show hosts (the "Heavy Hundred") in America by TALKERS Magazine.
