In the 1960s and '70s, CKLW was one of the most important rock & roll radio stations in North America. Boasting a powerful 50,000-watt signal that beamed out of Windsor, Canada (just across the border from Detroit, MI), CKLW could be heard all across the Midwest, and music director Rosalie Trombley's ear for a hit song helped give more than a few major artists their first few hits, among them the Supremes, Mitch Ryder, Elton John, Alice Cooper, and many more. Playing the best pop, rock, and R&B of the day and featuring high-energy DJs who squeezed plenty of personality into their snappy introductions as they played as many songs per hour as possible, CKLW (also known as the "Big 8" since it was at 800 on the AM dial) helped set the trends for Top 40 radio in its golden age. Radio Revolution: The Rise and Fall of the Big 8 is a documentary which looks at CKLW's glory days, as well as the circumstances that turned CKLW into an easy listening outlet in the mid-'80s. The film was screened to enthusiastic audiences at the 2004 South by Southwest Film Festival. ~ Mark Deming, All Movie Guide
