The Ed Sullivan Show was an American TV variety show that ran on CBS from Sunday June 20, 1948 to Sunday June 6, 1971, and was hosted by New York entertainment columnist Ed Sullivan.[1] It was replaced in September 1971 by the CBS Sunday Night Movie, which ran only one season and was eventually replaced by other shows.

WHHQ's history can be traced back as early as April 17, 1947, when the station first signed on the air as AM 1210 WKNX, owned by Lake Huron Broadcasting. The station was like many of its day, programming a full-service format of music, news, and talk. For many years, it was also a leading Top 40 hit music station in Saginaw, competing with WSAM (1400 AM) and Flint's WTAC (600 AM, now WSNL).

Among the station's history was the acquisition of a sister television station in the 1950s, and was also the radio home of 50's country music artist "Little" Jimmy Dickens. WKNX's resident "legend" would take form of University of Cincinnati graduate Robert Dyer, who joined the station in 1950 and remained a part of its staff for more than half a century. The following year, in 1978, WKNX underwent a major change when it was purchased by Radiocom Limited, a company headed by Robert Dana McVay. WKNX's city of license was immediately changed to Frankenmuth, and the station's studios and offices were moved to 306 West Genesee Avenue in Frankenmuth, where it was joined by a Tuscola-licensed sister FM station, WGMZ-FM (now WWBN), which programmed beautiful music. (The WGMZ calls and format moved from 107.9 FM, which became WCRZ "Cars 108" in 1984.) By the early 1990s, WKNX-AM was programming big band music and adult standards.

Radiocom owned WKNX and leased WGMZ (which would later became country-formatted WKMF and move its operations to Flint) until 1994, when WKNX was purchased by Detroit-based Bell Broadcasting Company in a frequency swap involving another AM station in Bay City (1250 WXOX) which had been silent since the early 90's.

Bell Broadcasting owned WCHB, an AM station licensed to Taylor, which operated at a daytime signal of 25,000 watts and a nighttime signal of 1,000 watts. WCHB was a talk station targeted to an African-American audience. The company's intent was to acquire WKNX's dial position at 1210 and silence it in order to provide WCHB with a 50,000 watt daytime signal. WKNX would then acquire the license of WXOX, which had first signed on in 1956 as a station first licensed to Essexville. Over time, the 1,000 watt station, operating at 1250 kHz, began broadcasting from Bay City with its co-owned Pinconning-licensed FM sister at 100.9. By the end of the 1980s, both stations had run into financial trouble and fell silent. 100.9 was spun off to a new owner a year later, but WXOX remained silent.
