ELI5: Why is it that television shows from Britain seem to appear different than American tv shows?

Can't quite put my finger on it... something to do with the cameras?

Couple things would give it a different look. First, they use PAL rather than NTSC. Pal uses 25 fps while ntsc uses 30 so pal will look more cinematic while ntsc will look more fluid. Also color encoding differences between pal and ntsc. 

When we in the U.S. watch a Britcom or other material produced in the UK, there will be some kind of conversion that takes place. The difference you see is mostly because of the conversion process.

The above refers to analog signals. Digital signals typically look more consistent between US and UK. Take a show like The Graham Norton show. It looks like it's produced in the US. The colors are on, no frame rate adjustment... All good. 

Btw the frame rate (25 vs 30) is due to the in-country electrical system. In the U.S., our AC runs at 60Hz. While in the UK, they run at 50Hz. So the frame rate is a multiplier of the AC cycles. 

If you're looking for less subtle differences, they spell things differently. So you'll see honor spelled honour; color spelled colour; and other spelling variances.
