Rivalry Years: 1966-1968

As partners, Cosby and Culp chased bad guys on the groundbreaking secret-agent show, which aired for three seasons from 1965-1968. But the stars were pitted against each other in the Best Actor in a Dramatic Series category for three straight years — and Cosby won each time they faced off, making him not only the first African-American to have a lead role in a dramatic series, but also the first to win the high-profile award.
