Running time

In the United States, dramas produced for hour-long time slots typically are 37–42 minutes in length (excluding advertisements), while sitcoms produced for 30-minute time slots typically are 18–21 minutes long. There are exceptions: subscription-based TV channels, such as HBO, Starz, Cinemax, and Showtime, have episodes that are 45–48 minutes long, similar to the UK. Audience opinions of length have varied due to factors such as content overload.

In Britain, dramas typically run from 46–48 minutes on commercial channels, and 57–59 minutes on the BBC. Half-hour programs are around 22 minutes on commercial channels and around 28 minutes on the BBC. The longer duration on the BBC is due to the lack of advertising breaks.

In France, most television shows (whether dramas, game shows or documentaries) have a duration of 52 minutes. This is the same on nearly all French networks (TF1, France 2, France 5, M6, Canal+, etc.).
