What are the longest-running TV series, by state (predominant location of the series)? Let’s stick with fiction series (so no 60 Minutes or SNL) that take place largely in a single specified location (so The Simpsons is out)
To get things started:
California - Knots Landing (14 years)
Colorado - South Park (14 years)
Hawaii - Hawaii Five-O (12 years)
Illinois - ER (15 years)
Kansas - Gunsmoke (20 years)
Massachusetts - Cheers (11 years)
Nevada - Bonanza (14 years)
New York - Law & Order (20 years)
Texas - Dallas (13 years)
Washington - Frasier (11 years)
Wisconsin - Happy Days (11 years)
Feel free to add on (or correct any mistakes I’ve made)
