CKLW is a 50,000 watt, Class B, AM radio station broadcasting on the Mexican clear-channel frequency of 800 kHz (800 AM) and located in Windsor, Ontario, Canada, serving Windsor and Detroit. Additionally, its signal can be heard as far west as Grand Rapids, Michigan; as far east as Batavia, New York (and, at night, Boston, Massachusetts); as far south as Edgewood, Kentucky; and as far north as Posen, Michigan. CKLW uses a five-tower directional antenna with differing patterns day and night, to protect Class-A clear-channel station XEROK-AM in Ciudad Juárez, Mexico, and other neighboring stations on the same frequency.

It is best known for having been one of the most influential Top 40 stations in the world in the 1960s and 1970s. During this era, CKLW used a very tight Top 40 format known as Boss Radio, devised by radio programmer Bill Drake. However, CKLW never actually used the handle "boss" on the air, just the style. Rather than a "Boss 30", CKLW's weekly music survey was known as a "Big 30". And instead of calling itself "Boss Radio", CKLW called itself "The Big 8". During this period it was the top-rated radio station not only in Windsor, but across the river in Detroit, and even in cities as far away as Toledo and Cleveland in Ohio.
