Sunny 104.5 Signs-Off

August 10, 2006 will go down as one of the most historical days in Philadelphia radio history. At Noon, Clear Channel blew up the formats of two of their five FM stations simultaneously. While Smooth Jazz was disappearing from 106.1 WJJZ, 104.5 WSNI was saying goodbye to its Gold based AC format. In both of their places appeared Rhythmic AC “Philly’s 106.1”. It wasn’t a simlucast persay, as FCC regulations forbid two stations with identical coverage from duplicating so much programming, however the same songs played in the same order with different sweepers and commercials leading to the music not lining up completely. The purpose of the so-called “shadowcast” was to get Sunny 104.5’s audience to move over to the new 106.1 format before the debut o...

“Groove 103.1” Signs Off

After “Groove 103.1” flipped back to Dance, the station’s ratings began to improve, albeit slightly. It eventually peaked at a 0.9 share 12+, which (tied with one of the previous formats on the 103.1 duo) represents the highest ratings ever achieved by the two 103.1 FMs. Apparently, this success got the attention of Jacor (now Clear Channel), owner of CHR/Pop KIIS-FM. In September 1998, Jacor purchased KACD and KBCD from Ken Roberts. Shortly thereafter, on October 12, 1998, Jacor switched “Groove 103.1” to a simulcast of KIIS-FM, and eventually debuted a AAA format under the name “Channel 103.1”. One side note: in an article which appeared on, KIIS-FM General Manager Roy Laughin admitted that Jacor bought Groove 103.1 and changed the fo...

The Final Hour of CHR on WAVA

In the early 1990’s, Emmis Broadcasting was one of the premier ownership groups in the country consisting of many stations of the former Doubleday and NBC Radio groups. However, one bad business decision (Ownership of the Seattle Mariners) caused the company to auction off many of its stations to the highest bidder. While WFAN in New York went to Infinity Broadcasting, some stations were unable to keep their current format by their new owners. Salem Broadcasting acquired WAVA and quickly stated its obvious intent to flip the station religious. WAVA had an illustrious history. One of the first FM all news stations in the 70’s, the station had been an AOR in the early 80’s when the decision to go Top 40 was made. Under such monikers as “All Hit 105”, “Powe...
