When CBS (?) decided that WOL-AM in Washington DC was not a viable radio station in the 1980s, the station was sold to her husband. She ended up with a child, no husband, and a radio station with no revenue to pay for staff. She essentially ran the station by herself for many years, sleeping in the station, raising her son.
In 1999, money became available during the post-’96 merger mania, as the FCC and Congress were pushing hard to empower black owned radio stations. She formed Radio One, and later Urban One, the syndicated Black Talk network that still employs activist Al Sharpton.
Once her son graduated from college and went to work selling advertising, things improved. Her son now runs the company which is publicly traded if you would like to own a piece of black radio.
