60 Minutes is an American television news magazine broadcast on the CBS television network. Debuting in 1968, the program was created by Don Hewitt and Bill Leonard, who chose to set it apart from other news programs by using a unique style of reporter-centered investigation. In 2002, 60 Minutes was ranked number six on TV Guides list of the "50 Greatest TV Shows of All Time", and in 2013, it was ranked number 24 on the magazine's list of the "60 Best Series of All Time". The New York Times has called it "one of the most esteemed news magazines on American television". Originally airing in 1968, the program began as a bi-weekly television show hosted on CBS hosted by Mike Wallace and Harry Reasoner. The two sat on opposite sides of the cream-colored set, though the set's color was later changed to black, the color still used today. The show used a large stopwatch during transition periods and highlighted its topics through chroma key—both techniques are still used today. In 1972, the program began airing from 6:00 p.m. to 7:00 p.m. Eastern time, although this time was sometimes disrupted by broadcasting of NFL games on Sundays. Since then, the show has generally kept the Sunday evening format, although the start time has occasionally been shifted. The program now generally starts at 7:00 p.m. Eastern. If sports programming is airing that afternoon, 60 Minutes starts at 7:30 p.m. Eastern or at the game's conclusion. The show is hosted by several correspondents; none share screen time with each other. Full-time hosts include Lesley Stahl, Scott Pelley, Bill Whitaker, and John Dickerson. Several spinoffs of the show have been made, including international formats of the show. Broadcast history Early years The program employed a magazine format similar to that of the Canadian program W5, which had premiered two years earlier. It pioneered many of the most important investigative journalism procedures and techniques, including re-editing interviews, hidden cameras, and "gotcha journalism" visits to the home or office of an investigative subject. Similar programs sprang up in Australia and Canada during the 1970s, as well as on local television news. Initially, 60 Minutes aired as a bi-weekly show hosted by Mike Wallace and Harry Reasoner debuting on September 24, 1968, and alternating weeks with other CBS News productions on Tuesday evenings at 10:00 p.m. Eastern Time.
