Slaight Communications is a Canadian radio broadcasting company. The company was formed as Slaight Broadcasting in 1971, when owner J. Allan Slaight acquired CFGM in Richmond Hill. Slaight later also acquired CFOX in Montreal and CHOK in Sarnia, and launched CILQ in Toronto. The company later sold off all of its original assets, and continued to operate its radio holdings through the Standard Broadcasting division after Slaight bought out that company in 1985. As Standard, it remained the largest privately owned multimedia company in Canada until it sold its radio and TV broadcasting assets to Astral Media in 2007. Today, all of Standard Radio stations are either owned by Bell Media or Stingray Radio. The company continues to operate holdings in non-traditional broadcast platforms such as satellite radio and Internet radio. Slaight also continues to hold minority investments in three other small radio station groups. Standard Broadcasting Standard Broadcasting was founded as Standard Radio Manufacturing in 1925 by Edward S. Rogers, Sr., but soon became known as Rogers Vacuum Tube Company and later became the Rogers Majestic Corporation Limited. Rogers launched what would become radio station CFRB in 1927 in order to demonstrate a batteryless alternating current radio receiver he had invented. In 1929 Standard Radio Manufacturing Corporation was renamed as Rogers Majestic Corporation Limited The broadcasting division of the company was renamed Standard Radio Limited in 1941 when the Rogers family sold off the assets of Rogers Majestic two years after the death of Edward Rogers. The Rogers family would later re-enter the broadcasting business in 1960 in a form of Aldred-Rogers Broadcasting, the company founded by Edward's son, Ted Rogers, which later became Rogers Communications. In 1945, Standard Radio was purchased by Argus Corporation and in 1966 Standard Radio Limited was renamed Standard Broadcasting. Argus was acquired by Conrad Black and his brother in 1978. Argus subsequently sold Standard to Slaight in 1985 and merged into Slaight Broadcasting.
