Baltimore's third television station first started on November 1, 1948 as WAAM. The station was originally owned by Radio-Television of Baltimore Inc., whose principals were Baltimore businessmen and brothers, Ben and Herman Cohen. 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 second day of operations, WAAM broadcast the 1948 presidential election returns and various entertainment shows, remaining on the air for 23 consecutive hours. Channel 13 has been housed in the same studio facility, located near Druid Hill Park on what was then known as Malden Hill (now known as Television Hill), since the station's 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.
