From Wikipedia:
M Squad was an American police drama television series that ran from 1957 to 1960 on NBC. Its format (and opening credits) would later inspire the creation of spoof TV show Police Squad!. Its sponsor was the Pall Mall cigarette brand, of which Lee Marvin, the program's star, appeared in its commercials during the episodes.
Set in Chicago, Illinois, it starred Marvin as Detective Lieutenant Frank Ballinger, a member of "M Squad," a special unit of the Chicago Police, assisting other units in battling violent crime city-wide. Paul Newlan co-starred as his boss, Captain Grey. Although Marvin had been appearing in feature films since 1951, it was this series that made him a star and he later went on to an even bigger film career afterward.
