WJZ-TV is the callsign for the CBS owned-and-operated affiliate in Baltimore, Maryland. It broadcasts on digital channel 13. It had previously aired on digital channel 38 (simultaneously with analog 13).
WJZ was the third station to sign on in Baltimore. It was ABC affiliate WAAM-TV at first and was the network's second affiliate nationally, with DuMont as secondary. It wound up under the ownership of Westinghouse Broadcasting (Group W) in 1957 and had its call changed to WJZ (the original call of what is now New York City's WABC TV and radio).
WJZ remained with ABC up until 1995 when the network signed an affiliation deal with The E.W. Scripps Company, owner of Baltimore NBC affiliate WMAR/channel 2. As a result, ABC moved to WMAR. Westinghouse subsequently signed an affiliation deal with CBS and moved its affiliation to WJZ (it had been on WBAL/channel 11, now an NBC affiliate). CBS bought WJZ outright in 1996.
As with several CBS east coast affiliates, WJZ airs the network's game show Let's Make a Deal at 10 AM, during the morning feed. Most CBS affiliates air it at 3 PM Eastern, when CBS feeds it then.
