Brown was born in Lawrenceville, Georgia in 1942. Bill Brown began his radio career at various radio stations, including San Diego Top 40 station 136/KGB (now KLSD). Brown began working on WOR-FM (now WEPN-FM) in 1966 doing various swing airshifts, eventually fitting full-time. Initially, WOR-FM was a progressive rock station, but it evolved into an adult top 40/oldies station by 1968.
In 1969, WCBS-FM traded in their easy listening 'Young Sound' format for an album rock format similar to WABC-FM (later WPLJ) and WNEW-FM. Brown was on the original airstaff. Unfortunately, WCBS-FM couldn't lay claim to sizable ratings in the New York City radio market while additional stations such as WNEW-FM and WPLJ gained most of the rock n'roll radio audience.
After research and several years of quite low ratings WCBS-FM dropped the AOR format on July 7, 1972 at 6 AM and began playing Oldies from 1955 to then current product. Initially the station played both rock and roll songs and non rock songs of the 1950s and early 60's and only softer rock and pop hits of the late 1960s and early 1970s. Brown, along with the rest of the airstaff including Don K Reed (who was hired in January 1972) all stayed on with the Oldies format.
Back then, it was common for airstaffs to stay on after format changes and not as common to lay off entire airstaffs. By the end of 1972, Brown was on the station weekdays 9 a.m. to 3 p.m. and Saturdays from 6 a.m. to 10 a.m.
Over the next few years most of the staffers of the station would leave, but Brown and Don K Reed stayed on and were still part of the station in 1974. In 1975, Brown additionally became Program Director of WCBS-FM. For a few months he gave up his midday airshift.
By the end of 1976, Brown was on from 10 a.m. to 2 p.m. weekdays along with his Saturday morning shift. Under Brown, WCBS-FM moved away from easy listening and began to play more 60's rock. In 1978, Brown gave up his programme director position but retained his airshifts. His shift was still 10 a.m. to 2 p.m. weekdays and 6 a.m. to 10 a.m. Saturdays.
In 1984, when Ron Lundy arrived, Brown was moved to 12 p.m. to 3 p.m. while Ron moved to the 9 a.m. to 12 p.m. slot. Harry Harrison now aired from 5:30 a.m. to 9 a.m. (previously he was on 6 a.m. to 10 a.m.). Bill's Saturday shift was then 6 a.m. to 9 a.m. every second week. Bill Brown additionally continued doing voiceovers for a large number of commercials airing on WCBS FM and additional radio stations. He celebrated 20 years in 1989, 25 years in 1994, and 30 years of service in 1999. In 1994, he officially dropped his Saturday morning airshift in honour of his a large number of years of service at the station.
As airstaff occasionally came and went (though staffers stayed a large number of years in most cases), Brown continued on consistently from noon to 3 p.m until 2005, when his airshift was moved to 1 p.m. to 4 p.m. weekdays. With his years of service, age, and retirements of additional well known staffers it was speculated that his retirement wasn't far off.
Bill Brown remained at WCBS-FM until the station's two-year "sabbatical", which started on June 3, 2005. Although ratings were decent and the station was profitable, CBS executives abruptly laid off the entire airstaff at 4 p.m. that day. Bill Brown was the last live air personality to sign off several minutes before 4 p.m.
He came out of Margaritaville by Jimmy Buffett and played Rescue Me by Fontella Bass. It was unclear whether or not he knew the end was happening from his last statement, though he didn't say a typical goodbye. His last words were, "CBS-FM 101.1, Fontella Bass... Do you ever feel the urge to just kinda scream "RESCUE ME!". I'm beginning to get that feeling, here's Fontella Bass." Other airstaffers definitely didn't know the end was near as they said goodbye and stated when they would be back.
Brown passed away on October 9, 2011 at the age of 69.
