Which company did Frasier's creators form to produce the show?

Frasier’s creators formed Grub Street Productions to produce the show. David Angell, Peter Casey, and David Lee established the company after working together as writers and producers on Cheers.

The partnership began before Frasier existed. The three collaborators left Cheers during its later years and created Wings, their first major series as a production team. When Kelsey Grammer’s Cheers character received a spin-off, Grub Street became the production vehicle behind Frasier. The company was affiliated with Paramount Television, which handled the studio relationship and distribution.

Grub Street’s name refers to Grub Street in London, a term historically associated with commercial writers and journalists. The company’s television work extended beyond Frasier: it also produced Wings and other NBC comedies, including The Pursuit of Happiness and Encore! Encore!. Frasier was additionally associated with Grammnet Productions in later seasons, which can cause confusion when viewers see multiple company names in the credits. Grammnet was a participating production company, but it was not the company Angell, Casey, and Lee formed together. Grub Street remained closely identified with the original sitcom until its 2004 finale.
