King of Queens launched on Pluto's Sitcom Legends channel, where Cheers and Frasier air. Also on the More Sitcoms channel, and on demand. I think that there are limited seasons.

The King of Queens heads to Paramount+ and Pluto TV (https://deadline.com/2024/04/the-king-of-queens-sony-pictures-television-licensing-paramount-plus-pluto-1235875585/)

While all nine seasons of the Kevin James 1998-2007 CBS comedy will be available on Paramount+ as part of licensing deal with Sony Pictures Television, only Seasons 1-3 can be watched on Pluto TV.
