Station history

CHUM AM has been broadcasting continuously since 1945, through a variety of format changes. The station's history can be broken into eight distinct eras, as follows:


The "full service" era: 1945-1957

CHUM was founded by four Toronto businessmen, including Al Leary, a former sportscaster, who had been the station manager at CKCL for 14 years. CHUM received its licence in late November 1944 to operate a station with 1,000 watts. CHUM launched as a dawn-to-dusk radio station on October 28, 1945, with John H.Q. "Jack" Part, an entrepreneur in the business of
patent medicines A patent medicine (sometimes called a proprietary medicine) is a non-prescription medicine or medicinal preparation that is typically protected and advertised by a trademark and trade name, and claimed to be effective against minor disorders a ...
, as its president. The station, operating from 1947 in studios at 225 Mutual St., broadcast a format typical of the late 1940s, with a combination of information, music, and sports. When CHUM was about to debut, Leary told the press that the new station would be known for community service and in-depth news, in addition to live talent and the most popular phonograph records. CHUM was taken over in December 1954 by Allan Waters, a salesman from Part's patent medicine business. Waters' first major move was to secure a licence for 24-hour-a-day broadcasting for CHUM, along with a power increase to 5,000 watts.


The Top 40 era: 1957-1986

Less than three years after Waters acquired the station, and soon after bringing the new full-time transmitter online, a major programming change was made. On May 27, 1957, at 6 AM, Waters switched the station to a " Top 50" format that had proven itself popular in some U.S. cities and issued the first

The station rose in popularity in Toronto in the late 1950s and early 1960s; though it never supplanted perennial Toronto ratings champ CFRB at the top of the ratings chart, it was still a major broadcasting powerhouse with a particular appeal to the teen market. As the station became more successful, it also built yet another new transmitter in Mississauga, Ontario (a few miles west of the current Toronto city line) along the Lake Ontario shoreline, and raised its power once again to its current 50,000 watts around the clock. In the late 1950s, CHUM was calling itself "Radio One", as its ratings continued to increase. An important part of CHUM's success was the station's unpredictable morning man Al Boliska, who joined CHUM in October 1957, after working at station CKLC in

Boliska also did a number of stunts, such as taking part in a professional wrestling match with Whipper Billy Watson.

He was replaced by WKBW Buffalo radio and TV personality Jay Nelson, popularly known as "Jungle Jay" from his role as host of a children's show on Buffalo's Channel 7 which was also popular among Toronto youngsters. He would be followed by housewives' jock John Spragge; singer/DJ Mike Darow; Pete Nordheimer, replaced in 1961 by Bob McAdorey, teen DJ Dave Johnson, and all night DJ Bob Laine. Later additions to the CHUM DJ lineup included Duff Roman and Brian Skinner, both of whom came from rival Toronto rocker CKEY (then owned by Jack Kent Cooke). In the late 1960s and early 1970s, CHUM DJs included Duke Roberts (also known as Gary Duke for a time), Johnny Mitchell (better known today as Sonny Fox), J. Michael Wilson, Tom Rivers, Scott Carpenter, Jim Van Horne, John Rode, Don Reagan, John Majhor, Mike Cooper, Daryl B, Terry Steele, Mike Holland and morning man Roger Ashby. Among their later night-time hosts was J. D. Roberts, who joined CHUM for a time in 1977, eventually becoming known across North America as White House correspondent for

In the 1950s and 1960s, it was contests such as 'The Walking Man', where listeners had to spot CHUM's mystery walking man using only clues given out on the air. The 1970s' "I Listen to CHUM" promotion had DJs dialing phone numbers at random and awarding $1,000 to anyone who answered the phone with that phrase. In 1976, there was the CHUM Starsign promotion. Listeners wore a button featuring their astrological sign. If CHUM's 'Starsign spotter' saw a person wearing his or her Starsign, that person won prizes such as money or concert tickets to major events. The

(This was later surpassed by Hamilton's CKOC, which published weekly charts from 1960-1992.) The first CHUM Chart was released on May 27, 1957, with Elvis Presley's "All Shook Up" the first Number 1 song. RPM Magazine paid tribute to CHUM's 11th anniversary with their May 25, 1968, issue.


From top 40 to gold-based AC: 1986-1989

By the mid-1980s, CHUM had lost ground in the Toronto ratings to competing Top 40 station CFTR and FM-based music stations. On June 6, 1986, at 3 p.m., after playing Starship's " We Built This City", CHUM dropped its

. The change also discontinued the CHUM Chart, which ended the week of June 14, 1986, with Madonna's " Live to Tell" as the final Number 1 song. By January 1989, the station had evolved into a brighter adult contemporary format ("Toronto's Soft Rock"), focusing on pop hits from the past decade and dropping much of the older music. While the adult contemporary format started off with modest ratings, CHUM began to slip further over the next few years; in the September 1989 ratings book, CHUM was ranked 11th and held a 2.9 share of the Toronto market.

TSN Radio 1050: 2011-present

Shortly after the re-acquisition of CTVglobemedia by Bell Canada was announced in the fall of 2010, and with ''CP24 Radio 1050'' not proving to be successful, media analysts began to speculate that CTV would be converting many of its existing AM radio stations including ''CP24 Radio 1050'' into a national sports radio network co-branded with its sports television channel TSN sometime in 2011, which would compete against rival Rogers-owned Toronto radio station, The Fan 590, as the two stations previously did from 2001 to 2002. The plans were unveiled on February 17, 2011, when CTV announced that CHUM would drop its CP24 simulcast and flip to sports radio as '' TSN Radio 1050'' on April 13, 2011, the first station under the newly formed brand. TSN considered the flip to be a "soft launch" for the TSN Radio brand, expecting a full launch with more local programming by September."Ground shifting as broadcasters brace for sports war"
