WBRK (1340 AM) is a radio station licensed to serve Pittsfield, Massachusetts.
 WBRK was the Berkshires first radio station taking to the air in 1938 in studios located on "Bank Row" in downtown Pittsfield.
 As with many stations of that era, the spacious studios allowed for live performances by the big bands and orchestras of the day.
 The company later founded the only commercial television station to call the Berkshires home in the 1950s with WMGT.
 The television station, with a tower on Mount Greylock, was later sold and eventually evolved into WTEN-TV based in Albany, New York.
 The radio station is currently owned by WBRK, Inc.
 It airs a Soft Adult Contemporary (a contemporary form of Easy Listening without so-called "Elevator music") music format while airing CBS Sports Radio featuring Jim Rome and Doug Gottlieb.
 The station was assigned the WBRK call letters by the Federal Communications Commission.
WQED, VHF channel 13, is a PBS member television station located in Pittsburgh, Pennsylvania, United States.
 The station is owned by WQED Multimedia.

 WQED also became the first station to telecast classes to elementary school classrooms when Pittsburgh launched the Metropolitan School Service in 1955.
 WQED has been the flagship station for "Mister Rogers' Neighborhood", "Where in the World Is Carmen Sandiego?
" (in co-production with WGBH-TV), and "Daniel Tiger's Neighborhood" (its live action sequences were filmed in Pittsburgh).
In broadcasting, local insertion is the act or capability of a broadcast television station, radio station or cable system to insert or replace part of a network feed with content unique to the local station or system.
 Most often this is a station identification (required by the broadcasting authority such as the U.S. Federal Communications Commission), but is also commonly used for television or radio advertisements, or a weather or traffic report.
 A digital on-screen graphic ("dog" or "bug"), commonly a translucent watermark, may also be keyed (superimposed) with a television station ID over the network feed using a character generator using genlock.
 In cases where individual broadcast stations carry programs separate from those shown on the main network, this is known as regional variation (in the United Kingdom) or an opt-out (in Canada and the United States).

KNIK-LP is a low-power commercial television station in Anchorage, Alaska, broadcasting on VHF channel 6, taking advantage of that station's audio signal on 87.75 MHz FM.
 The station is one of very few low-power television stations that operate predominantly as a radio station by way of the fact that many FM radio receivers can tune in a VHF channel 6 television audio carrier at 87.75 MHz.
 This technique is made more potent due to a formerly unforeseen interpretation of deregulatory language in FCC low-power television station regulations:
