Mark VII Limited was the production company of actor, producer, and director Jack Webb, and was active from 1951 to Webb's death in 1982. Many of its series were produced in association with Universal Television; most of them aired on the NBC television network in the U.S. The Jack Webb estate now owns the rights to the library, with the exception of the original 1954 feature film version of Dragnet (originally released by Warner Bros., but now owned by Universal Pictures), and the films Pete Kelly's Blues and The D.I. (which are controlled by original distributor Warner Bros.).
