CBS
radio station
in Chicago, Illinois broadcasting on the AM
dial at 780 kHz. It is owned by CBS
along with WBBM-TV
.
The station is also simulcast
on WCFS-FM, 105.9 to provide better service to Chicago's central business district and better audio quality to the market in general, an arrangement that launched on August 1, 2011 after CBS discontinued WCFS's former AC format to ward off a challenge from new all-news station WWWN (101.1).

began an amateur spark station. In 1923, it received a commercial license and was assigned the frequency of 1300 kHz. It also received its current call letters, which stand for World's Best Battery Maker. In later years, an alternate meaning, "We Broadcast Better Music," was created.
The Atlasses sold their battery company in 1924 to devote their full attention to WBBM, and moved to Chicago that same year. It became a charter CBS affiliate in 1928. The new network liked what it saw in the station, and bought a controlling interest in 1929. Leslie Atlass remained station manager with a 33 percent interest. CBS bought the remaining stock in 1933. As part of the deal, Atlass became vice president of CBS' Central Division while remaining station manager of WBBM—positions he continued to hold until his retirement in 1959. A series of power increases over the years culminated in its current power of 50,000 watts in 1935, allowing the station to cover much of North America after dark. It had studios at various locations in Chicago until 1956. In 1956-2006, it operated from a converted arena on North McClurg Court, and in 2006 it moved to Two Prudential Plaza
.
The station has been all-news since 1968. From 1964 until 1968 the format was news/talk, and prior to that, the station had a MOR/Personality-based format. The station has been the flagship station of the Chicago Bears
since 2000, and in its history has also aired Chicago White Sox
and Chicago Blackhawks
games.
Over the years, WBBM fended off all-news competition from McLendon-owned WNUS and from WMAQ Radio, which came under the CBS umbrella when Westinghouse Electric Corp. purchased CBS in 1997; sports-talk WSCR took over the WMAQ frequency in 2000. For many years, WBBM Newsradio 780 has been in a spirited battle with rival news/talk/sports station WGN
for the number one AM or FM radio station in the Chicago media market. In the June 2009 Arbitron
ratings period, WGN held a slight edge over WBBM in PPM metered listenership ratings. However, since the Fall of 2009, WBBM has regained the lead while WGN began to slip.
780 is also known for a couple of trademarks. Typically before a commercial break the current on-air personality will claim, “WBBM news time…(current time of day)" (as is standard procedure with every other all-news station owned and operated by CBS). The station provides updates on traffic and weather "on the eights." Also after any sort of sports update the on-air personality will also proudly claim, “you're listening to the home of the Bears.” The station has also been the longtime flagship of the Chicago Air & Water Show
in mid-August every year as the station's anchor and reporting staff describe the sights of jets and airplanes doing stunts above the water off Chicago's lakefront to listeners.
According to the radio industry website, RadioStats (RadioStats.Net), WBBM's website is the most visited radio station website in America.
WBBM's skywave signal was received as far west as Salt Lake City, Utah. Additionally, hobbyists as far east as Scotland and Germany have claimed to have been able to pick up the station's broadcast.
