WFMJ-TV's studios are located on West Boardman Street in downtown Youngstown, and its transmitter is based in the city's Lansingville neighborhood.

The Maags then purchased the construction permit issued for channel 21 (originally granted to WUTV) and moved to that frequency on August 7, 1954.

In addition to its main service area of extreme northeastern Ohio and northwestern Pennsylvania, WFMJ-TV can be seen as far as the eastern and southern suburbs of Cleveland with a good antenna, which allowed access to NBC programming pre-empted by KYW-TV from 1956 until 1965, when Cleveland's channel 3 was owned by Westinghouse Broadcasting, before the sale was undone and it returned to NBC ownership as WKYC.

WFMJ-TV has been the only locally owned and operated station in the market since CBS affiliate WKBN-TV (channel 27) was sold off in 1997.

In fact, it is one of the few stations left in the country that is still locally owned and operated and one of three in Ohio, with the others being WBNX-TV in Akron and WCPO-TV in Cincinnati, with WBNS-TV in Columbus and WHIZ-TV in Zanesville having been sold off in recent years to Tegna Inc. and Marquee Broadcasting, respectively.

WFMJ is the Youngstown market's carrier station for the Ohio Lottery and its weekly game show, Cash Explosion Double Play.

Officially known as the Eastwood Mall Bureau, its primary focus is to cover news stories in Trumbull County, Ohio.

The subchannel launched in November 2004 as an affiliate of The WB (branded The Valley's WB),[8] and despite Youngstown's small market size (ranked #106 by Nielsen Media Research as of 2008[update]), WBCB was one of the nation's first digital subchannels whose programming did not consist of 24-hour weather information (such as NBC Weather Plus).
