On this week's quiz, we're talking about TV shows that lasted for nine seasons.

More often than not, the reason - other than popularity, of course - why TV shows last for nine seasons is often down to syndication. Usually, TV studios want enough episodes so that they can repeat them on a daily or weekly basis without audiences getting bored or flicking over too easily.
