CKWW

The original applicant for the CKWW licence was Royce Frith (later to be a Canadian Senator). But Frith sold the station to Geoff Stirling before it went to air. The station was launched by Stirling on March 29, 1964, signing on the air on March 30, 1964 .

Initially CKWW featured a middle of the road (MOR) or "good music" format with a heavy news and information commitment, making it the Windsor equivalent of Detroit's WJR. The morning host was Norm Aldred, with news delivered by Stan Switzer and sports with Al Shaver (who was also the station manager). Other disc jockeys included Ron Burgoyne in the afternoons and Richard "Dick" Gasparini hosting an all-night program called "Music 'til Dawn," at one point totally sponsored by a well-known tobacco company. Popular recording artists featured on a regular basis included Frank Sinatra, George Shearing, Peggy Lee, Andy Williams, Nat King Cole, the Four Freshmen and Barbra Streisand.

In 1967, sister station CKWW-FM was launched (later CJOM and now CIMX). Stirling sold the stations in 1984, and the station dropped its MOR music programming to adopt a news/talk format in 1989.

In 1993, CHUM Incorporated acquired CKLW and CKLW-FM as well. CKLW (by then a "Music of Your Life" adult standards station) and CKWW swapped formats, with CKLW becoming the news/talk outlet and CKWW adopting the adult standards format.

In 2005, CKWW changed its on-air moniker from "580 Memories" to "AM 580 Motor City Favorites." It dropped all jingles and added more uptempo hits from the 1960s through 1990s plus some adult contemporary chart recurrents while dropping most of its pre-1960 titles, in an attempt to appeal to a younger audience. The change in the music proved largely unpopular with fans of the old standards format.

In October 2006, in response to 104.3 WOMC eliminating the word "oldies" from its on-air positioning, CKWW revamped its playlist once more to focus primarily on music from the late 1950s through the late 1970s while dropping all post-1980 material. CKWW now plays many of the oldies hits originally heard during the Top 40 era of CKLW, then known as "The Big 8." Although still known as "AM 580, Motor City Favorites," the station returned jingles to its on-air presentation and added the taglines "Great Fun! Great Oldies!" and "All Oldies, All the Time" to its slogans.

AM 580 plays up its connections to Windsor/Detroit's Top 40 radio past on the air, as the station's top-of-the-hour identification mentions that the station "broadcasts from the legendary studios of "The Big 8" (at 1640 Ouellette Avenue in Windsor) and also features the widely recognized instrumental signature tunes from CKLW's glory years.

In 2007 CKWW along with the other CHUM stations were sold to CTVglobemedia. In 2011, CTVglobemedia was acquired by Bell Media.

In June 2012, CKWW began airing the syndicated American Top 40 - The 70s with Casey Kasem from 7-10 p.m. on Sundays and Tuesdays, but scaled it back in mid-2013 to a once-weekly broadcast in the Sunday evening time slot. Other weekend specialty programming includes Breakfast with The Beatles, Money Matters, Elvis Only!, Shake, Rattle, Showtime and the Sunday Oldies Show.

CKWW is the last remaining AM station under Bell Media ownership playing music as of 2010, when Winnipeg, Manitoba's CFRW went from oldies to sports.

On January 6, 2016, iHeartMedia announced that it had partnered with Bell Media to carry its radio stations on its iHeartRadio streaming platform, including CKWW.
