From February 10 to 26, 2006, NBC preempted its regular prime time schedule in order to air coverage of the 2006 Winter Olympics.
PBS is not included, as member television stations have local flexibility over most of their schedules and broadcast times for network shows may vary.
Each of the 30 highest-rated shows released in May 2006 is listed with its rank and rating as determined by Nielsen Media Research.
