On September 11, 2001, the transmitter facilities of Channel 11 as well as six other New York City television stations and several radio stations were destroyed when two hijacked airplanes crashed into and destroyed the World Trade Center towers.
WPIX-FM (101.9) was co-owned with WPIX-TV for over 30 years but was sold by the Tribune Corporation to Emmis Communications in 1988. WPIX-FM was famous for not being able to settle on a format for any real length of time and was derisively nicknamed "The format of the month station" by many in the radio industry and general public.
