I stumbled across a news story about Leno vs. O'Brien and it made me sit up and take notice of the times these 'late show' style programmes are on.

My question is, do folks in the US actually stay up until 2AM to watch these shows? By contrast in the UK the only thing on at that time of night is either a show of limited appeal, a repeat of a prime time show with in vision signing for the deaf or possibly a film. From reading the news item, it seems the shows are really popular. Do people in the US need less sleep? Or do you simply record it and watch it the day after. I'd never be able to get up for work if I was watching TV until 2AM.
