Alexander Graham Bell |
Bell's father, grandfather, and brother had all been associated with work on elocution and speech and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone in 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study.Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics.
AT&T Corporation was eventually purchased by one of its Baby Bells, the former Southwestern Bell, in 2005 and the combined company became known as AT&T Inc.
WWJ Control |
➦In 1922...WWJ-AM, Detroit, Michigan signed-on.
WWJ first signed on the air on August 20, 1920 under the call sign 8MK, and was founded by The Detroit News; the mixed letter/number calls were assigned to the station by the United States Department of Commerce Bureau of Navigation, the government bureau responsible for radio regulation at the time. The 8 in the call sign referred to its location in the 8th Radio Inspection District, while the M in the call sign identified that the station operated under an amateur license. It is not clear why the Detroit News applied for an amateur license instead of an experimental license. As an amateur station, it broadcast at 200 meters (the equivalent of 1500 AM).8MK was initially licensed to Michael DeLisle Lyons, a teenager, and radio pioneer. He assembled the station in the Detroit News Building but the Scripps family asked him to register the station in his name, because they were worried this new technology might only be a fad, and wanted to keep some distance.

On October 13, 1921, the station was granted a limited commercial license and was assigned the call letters WBL. With the new license, the station began broadcasting at 360 meters (833 AM), with weather reports and other government reports broadcast at 485 meters (619 AM).
On March 3, 1922, for reasons that are not known, the call letters, 'WWJ, were assigned to the station. Some believe the new call letters are an abbreviation for stockholders William and John Scripps, but on page 82 of a book published by the Detroit News in 1922, WWJ-The Detroit News, it stated that "WWJ is not the initials of any name. It is a symbol. It was issued to the Detroit News by the government in connection with the licensing of this broadcasting plant."Ty Tyson was the original “voice” of the Detroit Tigers was 39 years old that first radio summer of 1927.
