25. Law & Order (1990–2010)
The joke is that pretty much everyone—actors, musicians, even random New Yorkers—has made an appearance on one of the various Law & Order iterations at some point. The same could be said of New York City locales: In its decades on the air (as well as those of SVU and Criminal Intent), L&O filmed in far-flung corners of the city, lending the show an air of authenticity. And let’s not forget its ripped-from-the-headlines plotlines, including ones inspired by subway vigilante Bernhard Goetz and the murder of Kitty Genovese.—Amy Plitt
