The other four tournaments all date from 1980 or later, having been founded in the era when senior golf became a commercial success.
This occurred when the first big golf stars of the television era, men such as Arnold Palmer and Gary Player, began to reach the relevant age.
Unlike mainstream men's golf, the senior game does not have a globally agreed set of majors.
The table below shows the results of all the events designated as majors by the Champions Tour.
Winners of Senior PGA Championships played before December 1979 (from the 1980 to 1983 seasons, and again in the 1985 season, it was the winner of the Senior PGA Championship in December of the previous calendar year) and Senior Opens played before 2003 are not listed here as they were not Champions Tour majors at the time nor retroactively recognized as majors.
Bernhard Langer holds the record for the most senior majors won with twelve.
