List of most-watched television broadcasts

This article lists the television broadcasts that had the most viewers within individual countries, as measured by ratings and research agencies in those countries. The research methodology and choice of statistics varies between sources, and is explained in individual sections. Because many events are watched simultaneously around the world and recorded programs are exported to multiple countries, it is difficult to collate reliable figures for global audiences. Those countries where reliable figures are available may use incompatible methodologies, such as the minimum age of counted viewers, and what proportion of the program must be watched when measuring the "reach" of a program, rather than its average or peak audience.
