Yes. All in the Family was a January debut in 1971, starting lower, relatively speaking, than Empire -- more total viewers, but a lower rating/share. The series quickly built throughout the spring and summer of 1971 and roared back to life in the fall of 1971. AITF actually ranked #1 for five consecutive seasons beginning in 1971-72 with viewer totals that would be impossible in today's very different television universe. The Cosby Show would later tie AITF's record for five #1 seasons. Cosby doesn't really apply here though, b/c Cosby was an instant hit, ranking third overall its premiere week.
