By the 1950s, and continuing through the mid-1970s, many of the most powerful North American "clear channel" stations such as KDKA, WLW, CKLW, CHUM, WABC, WJR, WLS, WKBW, KFI, KAAY, KSL and a host of border blasters from Mexico pumped out Top 40 music played by popular disc jockeys.
After KLAC flipped to music, Marshall hosted her own show for a year on WWKB in Buffalo, New York, a 50,000 watt powerhouse heard throughout the northeastern United States and Canada.
