(Reuters) - Republican President Donald Trump and Democrat Joe Biden face off on Tuesday in a televised presidential debate, part of a 60-year-old tradition marked by some of the most memorable moments of modern U.S. political history:

- 1960: The first televised debate pitted Democratic nominee John F. Kennedy against Republican Vice President Richard Nixon, who was recovering from a hospital visit and had a 5 o'clock shadow, having refused makeup. The 70 million viewers focused on what they saw, not what they heard. Kennedy won the election.
