Its signal covers the Philadelphia metropolitan area and much of the Lehigh Valley region of eastern Pennsylvania and parts of New Jersey, Delaware, and Maryland.

On weekends, shows focus on money, health, law and real estate, some of which are paid brokered programming.

Mike Opelka, Jimmy Failla, Walter Sterling and Matt Rooney host talk shows on weekend evenings.

WPHT was the flagship station for Philadelphia Phillies baseball for 32 years, until the 2016 season, when co-owned 94.1 WIP-FM took over that role.

The 10 kW shortwave transmitter was disassembled, and WCAU staff were told that it was sent to England to aid the BBC war propaganda efforts.

However, the transmitter was actually sent to Camp X, a secret World War II paramilitary and commando training facility located near Toronto, Ontario, Canada, becoming part of the Hydra signals intelligence and communications program.

However, the Record folded shortly thereafter, and its "goodwill", including the rights to buy WCAU-AM-FM, passed to the Philadelphia Bulletin, which already owned WPEN and WPEN-FM, and had secured a construction permit for WPEN-TV (channel 10).

The Levys continued to run the stations while serving as consultants to the Bulletin, and it was largely due to their influence that WCAU-TV took to the air on May 23, 1948, as a CBS affiliate.

[12] This came because the Bulletin had recently bought WGBI-TV in Scranton, Pennsylvania and changed its call sign to WDAU-TV to complement WCAU.

However, the two television stations' signals overlapped so much that it constituted a duopoly under Federal Communications Commission (FCC) rules of the time.

All-news had earlier been established on WCBS in New York City, KNX in Los Angeles, and several other CBS AM stations.

A year later, CBS merged with Westinghouse Electric Corporation, thus making 1210 AM a sister station to its long-time rival, KYW.

[15] Realizing that WGMP would never be able to compete against WIP, CBS began phasing out the sports talk shows in the summer of 1996.

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.

Only a year later, WIP became a sister station to WPHT when CBS merged with its owner, Infinity Broadcasting Corporation, which was then part of Viacom.
