The "Hot Hits" concept really appeared to grow in popularity after WCAU-FM (98.1) in Philadelphia, which had been struggling through unsuccessful Urban, Oldies and Disco formats for over a decade, relaunched with Hot Hits on September 22, 1981, as "98 Now." With legendary personalities such as Christy Springfield, Terry "The Motormouth" Young, Scott Walker, Rich Hawkins, Bob Garrett, with Todd Parker and Billy Burke. Paul Barsky would join in Mornings a year later. WCAU-FM came to dominate as Philadelphia's first and only choice for non-stop hot hit music from 1981 to 1986. WCAU-FM ended when they flipping to Oldies as WOGL in 1987. Within a year of WCAU-FM debuting "98 Now," "Hot Hits" had moved west to Chicago's WBBM-FM, where the original staff included Steve Davis, Joe Dawson, Gary Spears, Dave Robbins, Bob Lewis, Frank Foster and Tony Taylor; and Detroit's WHYT (now WDVD), which both coincidentally were both on the 96.3 FM frequency and used the on-air name "96 Now."
