WJZ-TV, virtual and VHF digital channel 13, is a CBS owned-and-operated television station licensed to Baltimore, Maryland, United States. The station is owned by the CBS Television Stations subsidiary of CBS Corporation. WJZ-TV's studios and offices are located on Television Hill in the Woodberry section of Baltimore, adjacent to the transmission tower it shares with ABC affiliate WMAR-TV (channel 2) and NBC affiliate WBAL-TV (channel 11).

On cable, the station is available on Comcast Xfinity channel 23. In outlying areas of the market and on Verizon FiOS, DirecTV and Dish Network, it is carried on channel 13.


Early history (1948–1957)

Baltimore's third television station started on November 2, 1948 as WAAM. The station's original owner was Radio-Television of Baltimore, Inc., which was operated by a pair of Baltimore businessmen, brothers Ben and Herman Cohen.[2] Channel 13 was originally an ABC affiliate, the network's fifth outlet to be located on the East Coast. Until 1956, it carried an additional primary affiliation with the DuMont Television Network. On the station's first day of operations, WAAM broadcast the 1948 presidential election returns and various entertainment shows, remaining on the air for 23 consecutive hours.[3] Channel 13 has been housed in the same studio, located on what is now known as Television Hill, since its inception; the building was the first in Baltimore specifically designed for television production and broadcasting. As a DuMont affiliate, WAAM originated many Baltimore Colts games for the network's National Football League coverage.[4][5]

The Westinghouse Electric Corporation purchased WAAM from the Cohen brothers in May 1957.[6] Westinghouse took control of the station in August of that year, and changed its callsign to WJZ-TV the following month.[7] The WJZ call letters had previously resided on ABC's flagship radio/television combination in New York City, which changed its calls to WABC-AM-FM-TV in 1953. However, Westinghouse's history with that set of call letters went back even further, as it was the original owner of WJZ radio, the flagship station of NBC's Blue Network, which would eventually become ABC.

All of Baltimore's television stations had fairly short transmitter towers in the medium's early years. But in 1959, the three stations banded together to build the world's first three-pronged candelabra tower.[8] Constructed behind the WJZ-TV studios, it was the tallest free standing television antenna in the United States at the time of its completion. The tower significantly improved channel 13's signal coverage in central Maryland, and also added new viewers in Washington, D.C., Virginia, Pennsylvania and Delaware.[9]

Later ABC years (1948–1995)

Over the years, WJZ-TV frequently preempted ABC programming in favor of local shows and syndicated content from Westinghouse's broadcasting division, Group W (notably the former ABC daytime soap opera Dark Shadows, which WJZ-TV preempted during the mid-1960s). However, ABC was more than satisfied with channel 13, which was one of its strongest affiliates. Additionally, Baltimore viewers could watch ABC programs on Washington's WMAL-TV/WJLA-TV (channel 7), whose signal decently covers most of the Baltimore area.

From 1957 to 1964, one of the station's highest-rated programs was The Buddy Deane Show, an in-studio teen dance show similar to ABC's American Bandstand, which WJZ-TV also preempted in favor of the Deane program. Deane's program was the inspiration for the John Waters 1988 motion picture Hairspray and its subsequent Broadway musical version, which in turn has been made into a film.

WJZ-TV nearly lost its ABC affiliation in 1977, when the network briefly pursued WBAL-TV just as ABC became the most-watched broadcast network (in primetime) in the United States for the first time. However, WBAL-TV declined the ABC affiliation offer due to ABC's last-place network evening newscast offerings of the time (a situation that would improve in ensuing years), keeping ABC on channel 13.[10][11]

Switch to CBS (1995–present)

In 1994, ABC agreed to an affiliation deal with the broadcasting division of the E. W. Scripps Company, which resulted in three of Scripps' television stations becoming ABC affiliates. ABC agreed to the deal as a condition of keeping its affiliation on Scripps' two biggest stations, WXYZ-TV in Detroit and WEWS in Cleveland. Both stations had been heavily courted by CBS, which was about to lose its longtime Detroit and Cleveland affiliates to Fox. One of the stations that was tapped to switch was Baltimore's then-NBC affiliate, WMAR-TV. ABC was reluctant to include WMAR in the deal; it had been a ratings also-ran for over 30 years while WJZ-TV was one of the strongest ABC affiliates in the nation. However, not wanting to be relegated to UHF in two markets with few viable choices for a new affiliate, ABC opted to end its 46-year affiliation with channel 13 and move its affiliation to channel 2.[12]

Group W felt betrayed by ABC after so many years of loyalty, as channel 13 had been ABC's longest-tenured affiliate at the time (a distinction that now belongs to WJLA-TV). As a safeguard, it began to shop for an affiliation deal of its own. Eventually, Westinghouse agreed to a long-term affiliation contract with CBS, resulting in WJZ-TV and its sister stations in Philadelphia and Boston switch to CBS (Westinghouse's two other television stations, in Pittsburgh and San Francisco, were already CBS affiliates).[13] The affiliation switch, the second in Baltimore television history, occurred early on the morning of January 2, 1995.[14] As a result, channel 13 became the third station in Baltimore to affiliate with CBS. The network had originally affiliated with WMAR-TV in 1948 before moving to WBAL-TV in 1981. Westinghouse then bought CBS on November 24, 1995, making WJZ-TV a CBS owned-and-operated station. Notably, this marked the first time that CBS had wholly owned a station in the Baltimore/Washington corridor; it had been minority owner of WTOP-TV in Washington (now WUSA) from 1950 to 1955.

Since 1998, the station has been the default home station for the NFL's Baltimore Ravens (via the NFL on CBS), airing both of the team's Super Bowl victories in 2001 and 2013.

WJZ-TV has used its current stylized "13" logo, using a font face exclusive to Group W, since 1967. The only real change came in 2002, when it added the CBS eye to its logo; even with that, WJZ is one of several CBS O&Os that use their call letters as their primary brand rather than CBS. Historically, WJZ has not followed the corporate branding styles used by other CBS O&Os.

"Presenting our future" (2017–present)

In January 2018, some minor changes began as the station adopted a silver and gold-colored logo similar to its sister stations, but with the WJZ calls displayed in a similar manner to sister station WBZ-TV. New music was added as well along with a new opening montage.[15]

Many viewers were aware of some possible changes at the WJZ studios as the morning show moved to the main news desk from the second studio and the "Pet Fridays" segment during the noon newscast was moved to the steps of the building. This led viewers to believe that WJZ was in line for a new set for the first time in 20 years. Since the CBS/Westinghouse merger, WJZ long had greater autonomy and control of its station during the Newman era than other CBS O&Os. For the first time, on August 2, 2018, a commercial tease talked about "presenting our future"[16] which showed a brand new set which falls in line with the CBS O&O sets. The new set debuted during the noon newscast on August 9, 2018.[17]

Analog-to-digital conversion

WJZ-TV shut down its analog signal, over VHF channel 13, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition UHF channel 38 to VHF channel 13 for post-transition operations.[20][21][22] WMAR-TV took over the channel 38 allocation as it moved its digital signal from channel 52 as a result of the phaseout of channels 52-69.

The switch caused problems for some viewers due to reception issues related to the transition, but the Federal Communications Commission granted WJZ-TV a power increase that helps some people.[23]

On October 21, 2014, CBS and Weigel Broadcasting announced the launch of a new digital subchannel service called Decades, scheduled to launch on all CBS-owned stations in 2015, including on WJZ-TV on channel 13.2. The channel will be co-owned by CBS and Weigel (owner of CBS affiliate WDJT-TV in Milwaukee), with Weigel being responsible for distribution to non-CBS-owned stations. It will air programs from the extensive library of CBS Television Distribution, including archival footage from CBS News.[24]

As a part of the repacking process following the 2016–2017 FCC incentive auction, WJZ-TV will relocate to VHF channel 11 by 2020, using PSIP to display its virtual channel number as 13.[25] Because WBAL-TV is currently on channel 11, WBAL-TV will move to channel 12 to allow WJZ-TV to move to that channel.


WJZ-TV is the Baltimore area affiliate of the It's Academic high school quiz competition. Channel 13 has also served two stints as the television home of the Baltimore Orioles baseball team, from 1954 to 1978 and from 1994 until 2017. It was one of the few "Big Three" stations that airs baseball on a regular basis.

Since becoming a CBS affiliate, WJZ-TV has carried the network's lineup in pattern with virtually no pre-emptions except for breaking news emergencies and Orioles baseball games, as per an agreement between Group W and CBS. Syndicated programming carried on the station includes Maury, Dr. Phil and Entertainment Tonight. WJZ-TV is the only CBS O&O station in the nation to carry the former show. The last two shows are distributed by CBS' corporate cousin, CBS Television Distribution.

News operation

WJZ-TV presently broadcasts 37 hours, 25 minutes of locally produced newscasts each week (with 6 hours, 35 minutes on weekdays; three hours on Saturdays; and two hours on Sundays). Like other CBS-owned stations, channel 13 offers a web-only newscast, WJZ At Your Desk, which is produced each weekday.

Soon after Westinghouse bought WJZ-TV, it significantly beefed up the station's news department. On October 12, 1957, WJZ-TV camerman John Kelly filmed a motion picture of the final stage of Sputnik 1's rocket crossing the pre-dawn sky of Baltimore, featured in a half-hour special program on Sputnik, broadcast that evening by Westinghouse sister station WBZ-TV in Boston.[26] Within a few years, it passed WMAR-TV for second place. Like the other Group W stations, WJZ-TV adopted the Eyewitness News format pioneered at Philadelphia sister station KYW-TV. By the early 1970s, WJZ-TV had passed WBAL-TV for first place—a lead it held for over 30 years. Around 2001, however, WBAL-TV passed WJZ-TV for first place in all evening timeslots, though WJZ-TV still placed a strong second. However, in the official November 2009 Nielsen ratings sweeps period, the first since the debut of The Jay Leno Show (which aired on WBAL-TV), WJZ-TV returned to a dominant position at 11 p.m. for the first time since the early 2000s. Both stations spent the next two years in a virtual dead heat in the late news. However, since the November 2011 Nielsen sweeps period, WJZ has dominated over WBAL in all news time slots in both total households and the critical 25-54 demographic; however, WBAL remains a strong second. It has been one of CBS's strongest O&Os ever since the 1995 affiliation switch.

WJZ-TV was the first station in Baltimore to hire a full-time consumer reporter, as well as the first station to organize an investigative reporting team. In 1965, shortly after it adopted the Eyewitness News format, Wiley Daniels became the first African-American anchor in Baltimore. He worked alongside Jerry Turner, one of the most popular anchormen in Baltimore television history. Al Sanders succeeded Daniels in 1977; he and Turner were the top news team until Turner succumbed to esophageal cancer. Denise Koch succeeded Turner upon his death in 1987; she remains at the anchor desk alongside Vic Carter, who succeeded Sanders following the latter's death in 1995.

In 1976, Oprah Winfrey became an anchor for the station's 6:00 p.m. newscast. She also co-hosted channel 13's local talk show, People Are Talking with Richard Sher, which premiered on August 14, 1978, and ran until she left for Chicago in 1983. The segment continues to run on the morning newscasts.

Since September 2008, The Baltimore Sun has had a news partnership with WJZ-TV; involving sharing content, story leads, and cooperating together on stories. Channel 13 promotes stories featured in the Sun on its news broadcasts. The Sun promotes WJZ's stories and weather team on its pages. Coincidentally, The Baltimore Sun was the founder and original owner of rival WMAR-TV from 1947 to 1986.

On October 25, 2009, WJZ-TV became the third Baltimore station to begin airing newscasts in high definition. For several months after the upgrade, field reports were still presented in 4:3 standard definition until it switched over to the 16:9 widescreen format. As of September 2011, all of WJZ-TV's locally produced video footage, including remote field reports, are in HD, making it the first station in Baltimore to do so.

During the Noon newscast on August 9, 2018, WJZ-TV unveiled a new set, and debuted a graphics package used by other CBS owned-and-operated stations.[27] On August 20, 2018, WJZ-TV expanded its morning newscasts from 5-7 a.m. to 4:30-7 a.m., becoming the last station in Baltimore to start their morning newscasts at 4:30.

Notable former on-air staff

Out-of-market coverage

In Delaware, WJZ is carried on Comcast in Sussex County. There is no coverage in most of New Castle County except in the area of Middletown for Atlantic Broadband cable subscribers. There is no coverage in all of Kent County. New Castle and Kent counties are part of the Philadelphia market, which also carries WJZ's sister station KYW-TV. Only Sussex County is part of the Salisbury, Maryland market which carries its CBS affiliate, WBOC. In the beginning of CATV, most if not all of Delaware once carried WJZ.[29]

In Maryland, the eastern shore communities of Cambridge, East New Market/Secretary, Pocomoke City, Ocean City, Salisbury and Snow Hill carry WJZ. These areas are in the Salisbury market which WBOC is carried. From Hagerstown and west towards Cumberland, WJZ is carried there as well in the far northwestern part of the Washington, D.C. market. Between Hagerstown and Cumberland, the towns of Hancock and Oldtown do not carry WJZ.

In Pennsylvania, it is carried in Greencastle, Delta, Hanover, Waynesboro and York County (but not in the city of York) which are in the HarrisburgLancaster–York market. In the Philadelphia market, it is carried in Oxford in Chester County.

WJZ is carried on cable in portions of Virginia located in the far western end of the Washington, D.C. market, alongside Washington's CBS affiliate WUSA. It is carried on cable in the Shenandoah Valley in Elkton, Front Royal, Luray and Winchester. In West Virginia, it is carried in the Martinsburg area; it is part of the Washington, D.C. market, which carries WUSA as well. In Keyser, Mineral County, WJZ is carried on cable.

During the 1970s and possibly the 1980s with CATV, WJZ was once on the cable lineups in Salem and Cumberland counties in southwestern New Jersey.[29]

WJZ's former analog signal could be picked up via antenna as far west as Warrenton and Culpeper, Virginia and as far east as Salem County, New Jersey. There is no satellite coverage outside of the Baltimore market for WJZ.
