WJAC-TV first began its broadcasting operations on September 15, 1949, originally owned by the Johnstown Automotive Company along with WJAC radio (AM 1400, later
WKGE at AM 850, and FM 95.5, now
WKYE at FM 96.5). At the time, it was the third-smallest television station in the country
market-wise to be granted a commercial license on or before December 31 behind
CBS affiliate
WNBF-TV in
Binghamton, New York, and fellow NBC affiliate
WICU-TV in
Erie. It originally aired an analog signal on
VHF channel 13 before moving to VHF channel 6 in 1952. Upon its sign-on, it aired programming from all four networks of the time (NBC, CBS, ABC, and
DuMont). CBS disappeared from WJAC-TV's schedule when WARD-TV (channel 56, now
Pittsburgh independent station
WPKD-TV on channel 19) signed-on in 1953 followed by DuMont when it shut down network operations in 1955. However, the station continued to air a few ABC shows until WWPC-TV (channel 23), a satellite of
Fox affiliate
WWCP-TV (channel 8), became ABC affiliate
WATM-TV in 1988. In the 1960s, Johnstown Automotive sold the WJAC stations to the estate of Anderson H. Walters, the owner of
The Tribune-Democrat, who held them until 1984 when tightened
Federal Communications Commission (FCC) cross-ownership regulations forced the newspaper to sell off the radio stations. The Walters estate sold off the newspaper to
MediaNews Group in 1987 but held on to Channel 6 until 1997 when it was sold to
Sunrise Television. WJAC and new sister station
WTOV-TV in the
Steubenville, Ohio–
Wheeling, West Virginia, market were sold to
Cox Enterprises in 2000. The two stations and
WPXI in Pittsburgh were occasionally marketed together as a result. WJAC-TV and WTOV were updated to WPXI's on-air graphics after being acquired by Cox, despite WPXI changing its own look in 2004. Most of the graphics introduced to WJAC-TV after the acquisition were used until October 2011, when WJAC-TV updated to WPXI's then-current look. When
KYW-TV switched to CBS on September 10, 1995, WJAC officially became the longest-tenured NBC affiliate in the Commonwealth of Pennsylvania. WJAC-TV gained a reputation for its locally produced programs at the station throughout the years.
Scholastic Quiz, a
game show featuring local high school students, and
Seniors Today (a
public affairs program targeted to those 65 and older) would become mainstays of the station's programming and make host Ron Lorence (who would later build WADJ, later
WBHV, at 1330 AM and then buy WYSN-FM 101.7, now
WOWQ in
Somerset County) a local household name. The station was also one of the stations across the country to produce a local version of the children's TV show
Romper Room. In the 1950s and 1960s, WJAC-TV's slogan was "Serving Millions from Atop the Alleghenies". On September 15, 2009, WJAC-TV celebrated its 60th year of broadcasting. During that month, WJAC-TV aired several commercials advertising the anniversary. One featured a variation of the "Serving Millions from Atop the Alleghenies" slogan creating "Serving Millions Across the Alleghenies". This old slogan was used in various ways in the station's broadcasts and mixed with the station's then-current slogan "Coverage You Can Count On" to form "Coverage You Can Count On Across the Alleghenies" the year before. On July 20, 2012, one day after Cox purchased four television stations in
Jacksonville, Florida, and
Tulsa, Oklahoma, from
Newport Television, Cox put WJAC-TV, WTOV-TV, and sister stations in
El Paso, Texas, and
Reno, Nevada, plus several radio stations in medium to small markets, on the selling block. All four of the television stations were located in markets that were smaller than Tulsa. On February 25, 2013, Cox announced that it would sell the four stations to Sinclair Broadcast Group. The FCC granted its approval of the sale on April 29, and it was consummated on May 2. This made WJAC-TV a sister station to nearby
WPGH-TV and
WPMY in Pittsburgh though it is still connected to WPXI-TV through a news-share agreement. On July 22, 2013, Horseshoe Curve Communications agreed to sell WWCP-TV to
Cunningham Broadcasting for $12 million. The Sinclair Broadcast Group was to operate the station through
shared services and joint sales agreements. However, the majority of Cunningham's stock is held by the Smith family (owners and founders of Sinclair). As a result, Sinclair would have effectively owned WWCP as well. As WWCP's long-standing local marketing agreement to operate WATM-TV was part of the deal, it would have resulted in the major commercial television stations in the market being controlled by just two companies. It would have essentially made WJAC-TV, WWCP, and WATM all sister stations and expanded on their existing news share arrangement (see below). However, on February 20, 2014, Horseshoe Curve informed the FCC that the sale of WWCP had fallen through. ==Subchannel history==
