What is the name of the NBC page played by Jack McBrayer on 30 Rock?

The NBC page played by Jack McBrayer on 30 Rock is Kenneth Parcell. Kenneth is a relentlessly cheerful, obedient employee who works at the network and becomes closely involved with the staff and cast of TGS.

He first appears as the page who helps maintain order around the NBC building, but his duties quickly expand. Kenneth becomes Tracy Jordan’s personal assistant and a loyal member of Tracy’s entourage, alongside characters such as Grizz and Dot Com. His devotion to television is one of the show’s recurring jokes.

Kenneth is sometimes confused with Jonathan, who is Jack Donaghy’s assistant, or with Grizz and Dot Com, who are associated with Tracy. Unlike those characters, Kenneth is specifically the NBC page. By the end of the series, his improbable career path takes him all the way to the presidency of NBC.
