On September 21, 1965, shortly after Westinghouse regained control of 1060 AM, the newly revived KYW dropped its NBC radio affiliation.
It became one of the first radio stations in the country to switch to an all-news radio format.
Newscaster Steve Porter read the first newscast, which had been edited by Fred B. Walters, the former Harrisburg bureau chief and eventual Executive Editor.
The new format was part of Westinghouse's decision to put all-news formats on its large market AM stations.
Five months earlier the company had converted 1010 WINS from a Top 40 format to all-news.
A third conversion was made three years later at another Westinghouse-owned station, KFWB in Los Angeles.
The Westinghouse trio of all-news stations made numerous contributions to developing the all-news format.

 In 1972, KYW moved to new studios in Independence Mall East, at Fifth and Market streets, where they would remain for the next 35 years.

KYW has long been a leader in the Philadelphia radio market, although its audience has naturally reduced due to the decline of AM as a whole.
KYW-TV took advantage of the radio station's popularity by incorporating a version of KYW's musical sounder into its news themes from 1991 to 2003.
In addition, a television simulcast of KYW's 5 to 8 a.m. block called KYW Newsradio 1060 This Morning aired on co-owned Channel 57 WPSG in the early 2000s, adapting KYW's "news blocks" to television.
KYW anchors and reporters were seen on morning television delivering the news.
