WJAC-TV first began its broadcasting operations on September 15, 1949 originally owned by the Johnstown Automotive Company along with WJAC radio (AM 1400, now 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 WBNG-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's schedule when WARD-TV channel 56 (now Pittsburgh's CW affiliate WPCW 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 into the 1980s. 
In the 1960s, Johnstown Automotive sold the WJAC stations to The Tribune-Democrat who held them until tightened Federal Communications Commission (FCC) cross-ownership regulations forced the newspaper to spin-off its broadcasting properties in 1982. Two years later, the new owner of WJAC-TV sold off the radio stations. Channel 6 was subsequently sold to Sunrise Television in 1997 before being acquired by Cox in 2000 who also added Wheeling, West Virginia/Steubenville, Ohio NBC affiliate WTOV in the same deal. The two stations and WPXI in Pittsburgh are now occasionally marketed together as a result.
WJAC 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-AM now WBHV at 1330 AM and then buy WYSN-FM 101.7 now WCCL in Somerset County) a local household name. In the 1950s and 1960s, WJAC's slogan was "Serving Millions From Atop the Alleghenies."
After the analog television shutdown and digital conversion that took place on June 12, 2009 , WJAC remained on its current pre-transition UHF channel number 34.  However through the use of PSIP, digital television receivers will display the station's virtual channel as 6. The nearby mountain ridges had prevented most of Altoona and all of State College from receiving the analog signal. Because the audio portion of VHF channel 6 was transmitted at 87.75 MHz, it was possible to listen to the television station on most standard FM car radios (or any standard FM radio for that matter). This was a feature frequently employed by area residents. However, this is no longer an option after the digital conversion.
 Out of Market Coverage
WJAC-TV is carried on various cable systems in several counties that are located outside of the Johnstown-Altoona market. These counties include Armstrong, Butler, Clarion, Indiana and Westmoreland.   In West Virginia, it is carried in Petersburg (93 miles away), Dorcas, Moorefield and Keyser.
 60th anniversary
On September 15, 2009, WJAC celebrated its 60th year of broadcasting.  During that month, WJAC 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 has been used recently in various ways in broadcasts and is now mixed with the station's most recent slogan "Coverage You Can Count On" to form "Coverage You Can Count On Across the Alleghenies."
 News operation
Current WJAC-TV News open.In the late 1960s and 1970s, WJAC had a fifteen minute long news and weather show weekday afternoons at 1 known as The News Today. Its 6 o'clock newscast was known as The News Tonight and the 11 p.m. broadcast was entitled 11th Hour News. The weather segment aired first and was titled "Weather in Motion" with its own sounder and graphics. The sports had a separate theme and was called "Sports Wrap Up." WJAC's weekday morning newscast began as a half-hour broadcast at 6:30 in 1985. In 1987, TCI Cable (now Comcast) in Centre County began producing a WJAC newscast, known as the Centre County Report, specifically targeted to that area.
On November 28, 2007, The Tribune Democrat reported that the shared news department of Fox affiliate WWCP-TV and ABC affiliate WATM-TV was going to shut down.  Under that operation, WWCP had produced an hour-long 10 p.m. news starting in 1992. However, according to a written statement, WWCP and WATM had been operating at a loss for years and the move was needed. The closure resulted in all personalities being released from their contracts. WJAC had on-air positions open but no personnel from those two stations were hired.
Effective January 14, 2008, WJAC assumed production responsibility of the 10 o'clock broadcast on WWCP (still known as Fox 8 News at 10) which was reduced to 35 minutes on weeknights and thirty minutes on weekends. The WJAC-produced news uses the same music package and some voice-overs seen during segment opens as the former operation had. A new graphics package slightly different from WJAC and new logos similar to the WWCP promo logo introduced in 2007 were created specifically for the primetime broadcast.
Because WJAC has prior commitments with news and weather cut-ins during Today, WATM still produces its own Good Morning America news and weather cut-ins that are seen Tuesday through Saturday. Former WWCP co-anchor Sherry Stalley, who was still under contract when the news department shut down, hosts the updates. The cut-ins use news video from the previous day's WJAC-produced WWCP broadcast and the same graphics package. On Mondays, the cut-ins are filled by WATM promos. In addition, WJAC's nightly 11 o'clock newscast is simulcasted on that station branded as ABC 23 News.
On August 8, 2008, WJAC unveiled a new set designed by FX Group in Orlando, Florida. The station also unveiled a new graphics package and changed its on-air branding from its long standing "Channel 6" to "WJAC-TV" as different cable companies now carry the station on different channels. In addition to its main studios, the station operates bureaus in State College (on West College Avenue (PA 26)), Altoona and DuBois.
