In 1922...WRR-AM, Dallas, Texas began broadcasting.
WRR-AM actually dates back to 1921 as the wireless operation of the Dallas Police and Fire Departments.
The station received a formal license as a "land station" from the Bureau of Navigation on August 4, 1921, and was assigned the call letters "WRR". In later years, the call letters would be said to stand for “Where Radio Radiates”. According to WRR’s original license, the station operated with a “composite” transmitting system (i.e. “homemade”), and was authorized to operate at a power of up to 100 watts, giving the station an approximate range of 200 nautical miles.
According to DFW Radio Archives, there were often long stretches of time when there were no fire or police calls to broadcast, so to ensure the equipment was indeed working (and perhaps satisfy their own curiosity with the strange new device), the dispatchers started to resort to other means of occupying the airwaves. They would read articles from the Dallas News or Herald, read letters, and tell jokes. Soon they had even brought in a phonograph player to place next to the microphone and send music over the airwaves.
A small but growing audience became fascinated by the magically transferred voices and music – these were the very beginnings of radio in north Texas.
WRR soon began to evolve into a “real” radio station. WRR’s initial license was issued through the Bureau of Navigation and fell into a categorical no-man’s land - while operating as a “broadcast” station, it was licensed as if it were a point-to-point operation. WRR did not receive a true broadcast license from the Commerce Department's Radio Division until March 13, 1922.
WRR-FM signed on in 1948, playing classical music. WRR-AM focused on popular music until it switched to all-news in 1975.
Bonneville Broadcasting bought the station in 1978. It became KAAM. It became all-sports KTCK in 1994. Today, Cumulus Media owns “Sports Radio 1310: The Ticket.”
The city kept WRR-FM, which remains on the air as a classical station. Taxpayers do not sustain WRR. It operates commercially, depending upon advertising revenue.
In 1938...First “World News Roundup” on CBS Radio.
The CBS World News Roundup is the longest-running network radio newscast in the United States. It airs weekday mornings and evenings on the CBS Radio Network.
When the show first went on the air it was hosted by veteran radio personality Robert Trout. The first show gave the world the voices of Edward R. Murrow and William L. Shirer. In fact, it was the first time Murrow had ever delivered a news report. During the early years of the war, Murrow's reports from London and Shirer's reports from Berlin were essential listening to anyone trying to keep informed on events unfolding in Europe.
The program was a 38-minute special report from multiple locations around the world as the pre-war crisis mounts. It was the first time that on-the-scene European field correspondents were linked with a central anchor in New York for a national broadcast. A recording of the first episode, as well as some others, is available at the Internet Archive.
Most broadcast references credit either CBS President William S. Paley or News Director Paul White as coming up with the idea for the show, as a way to trump Max Jordan's NBC coverage of the Anschluss. The previous day, Shirer had flown from Vienna to London at the request of Murrow (the CBS European chief) to give the first uncensored eyewitness account of Germany's takeover of Austria.
It was White who relayed the order to Murrow and Shirer for the first Roundup. The two, Murrow in Vienna and Shirer in London, then had the responsibility of linking up reporters and circuits that same day...a Sunday, when many of the key people would be mostly unreachable.
The format was so successful that it was repeated the following evening, and then revived later that year during the Sudetenland crisis. Eventually, it evolved into a daily show.
As World War II raged in Europe, the Roundup format spawned a weekend edition, The World Today. It was just before one 2:30 p.m. Eastern broadcast, on December 7, 1941, that White and World Today anchor John Charles Daly received word in New York that the Japanese had attacked Pearl Harbor. Daly's report at the top of the show, among the first on any radio station or network, is the one most often used in audio retrospectives.
