WJZ-TV, channel 13, is an owned and operated television station of the CBS Television Network, located in Baltimore, Maryland. 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 four other Baltimore television stations. It is one of four CBS O&Os that currently uses its call letters in its branding instead of "CBS", which would make the station name "CBS 13".

Baltimore's third television station started on November 2, 1948 as WAAM, owned by brothers Ben and Herman Cohen. Its first broadcast was the 1948 presidential election returns. Its studio was the first in Baltimore specifically designed for television. Channel 13 was originally an ABC affiliate; it was the second primary affiliate of the fledgling network. Until 1956, it carried a secondary affiliation with the DuMont Television Network, and originated many Baltimore Colts games for DuMont.

The Westinghouse Electric Corporation purchased WAAM in May 1957. Westinghouse took control of the station in August of that year, and renamed it WJZ-TV the following month. 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.

Al Sanders (March 13, 1941 - May 5, 1995), was an American, award winning, television news anchorman at WJZ-TV in Baltimore, Maryland. He helped take a third place television newscast to first place, where it stayed throughout his career.

In 1967 Sanders, as Al Gay, worked for radio station KXLW, in St. Louis, Missouri; in 1969 he changed stations and his name. His new station: KWK^{[disambiguation needed ]}, St. Louis, his new name: Al Sanders. Sanders joined WJZ-TV in 1972 and became a news anchor five years later. Prior to his arrival on Television Hill, WJZ's news was mired in third place in a town that had three major network newscasts: WBAL-TV was #1, WMAR-TV was #2. Three years later, WJZ with Jerry Turner, Sanders, Bob Turk (weather) and Nick Charles (sports) were a runaway #1, with more viewers than their competitors combined, and stayed there through the 70s and into the 80s. He continued alone after Jerry Turner died in 1987 and made Denise Koch a partner a year Later. Sanders won Emmy Awards in 1993 and 1994 for his regularly featured specialty report, "Picture This." Sanders died of lung cancer at the Johns Hopkins Hospital on May 5, 1995 and he was Replaced by Vic Carter (who is formerly of WSB-TV Atlanta).
