[3] He worked as an announcer at California radio stations KXO-AM, El Centro; KWIK-FM, Burbank; KIEV, Glendale; and KLAC-AM, Los Angeles.

Narz also made appearances in local Los Angeles television and served as the announcer on one of TV's first nationally broadcast children's shows, the 1950s science-fiction program Space Patrol.

[2] Narz first achieved television fame in 1952 as the on-camera announcer and narrator of the syndicated sitcom Life with Elizabeth starring Betty White.

[2] He returned to his role as on-camera announcer and narrator for a restaging of Life with Elizabeth (along with Betty White) for KCOP-TV's 50th anniversary special 13 at 50 in 1998.

Later that year, he was the host of Video Village, but asked producers to let him leave the show for personal reasons; Monty Hall succeeded him.

That year, Narz began hosting the syndicated revival of Beat the Clock, doing so until 1972 when the show's announcer, Gene Wood, replaced him.

His final game show work was hosting You've Got to Be Kidding, which was broadcast in the Los Angeles/metropolitan area on station KDOC-TV in Anaheim, California during the 1987–1988 season.
