History

Historical Context

ER, created by Michael Crichton, aired on NBC from September 1994 to April 2009, ending after 15 seasons and 331 episodes. Its finale drew 16.2 million viewers and marked the last major cast reshuffle, echoing earlier departures such as George Clooney’s late-1990s exit that began a cycle of character turnover. Networks continue this strategy, as seen in Chicago Fire’s 2026 senior-officer exits.
