I dont think the FCC has ever taken action like this...
They’ve pulled a few licenses here and there. A radio station in Central Pennsylvania for broadcasting racist Klan material in the 60’s. A TV station in Boston for its ownership being involved in unethical business practices in the 70’s. They may pull one in this area soon because a radio station owner was just convicted of a felony.
Generally though the stations appeal and the process drags on for years.
