There's also this one, arguing that NewsRadio was the best sitcom of the 1990s, albeit with the somewhat dubious argument that The Simpsons didn't count as a sitcom.
Yeah, even as much as I like NewsRadio, I'd have to give Seinfeld the nod as best sitcom of the 90's still. I understand not including The Simpsons because when I think of it and its episodes, it doesn't feel like the same beats and structure of a traditional sitcom. Likewise, if you were just to say best comedy of the 90's then I'd give that to The Simpsons as well.
Then there's the fact that NewsRadio lost Phil Hartman after the 4th season which does tarnish things a bit even though there is still some really funny stuff in the 5th season. To it's credit, I always found the Pilot a great episode, especially with its ending punchline, and the show starts off strong and doesn't really have to take a long time to find its footing. However, when comparing it to other shows, The Simpsons in the 90's rarely made any mis-steps and Seinfeld was able to have a longer sustained run and more influence and I really did enjoy them both.
However, nowadays, if I had to choose between watching an episode of Seinfeld or NewsRadio, I'd choose NewsRadio. Between The Simpsons and NewsRadio, it is 50/50 and depends on the episode of The Simpsons and how long since I've last seen it. Time has become kinder to NewsRadio it seems. The article makes a few good points as to why that is I think. I especially liked this line at the end: "It was a series that used these very old forms to tell a very new story about ... how tiny events (like a change in snacks or one person getting a new chair) can spin out of control into immense crises." That really sums up the show well.
Also helping NewsRadio is the way the series ended. Although part of me wonders what the show could have been like if it continued on by trying the idea of going from New York to small town radio considering how successful some shows have been when shaking up and changing the format of the show, at least it still ends on a pretty perfect note considering who stays and who goes from all that had come before on the series.
