Fun fact: because PAL runs at 25fps, whenever a British TV channel airs a standard format movie, they have to run the film 1/24th faster because you can't fit 24fps into 25fps.
Yes, this does mean that the sound is at a slightly higher pitch, too.
thankfully it's pretty easy to slow stuff down to 96% speed when you rip the dvd or w/e
24fps does fit into 50hz with computer output algorithms, but they needed a quick&dirty way back in the 70s (or,, whichever year) for the telecine machines
it's about 50/50 with modern dvd releases if they'll do a more advanced scale or a 104% playback speed

@dzuk yeah, there's a whole thing in the timescale modification world about pitch independent scaling for 24<->25, some of which is explicitly due to, uhh, people being unwilling to have footage of themselves released just-played-back-at-a-different-pitch because of perceived gender implications.
( even in the absence of formant preservation and stuff. )
The math of things helps NTSC and ATSC because 30/60 frames per second and the common denominator of 6, though some people end up noticing it in the form of perceived (but not actual) speedup.
Of course, because PAL is obsolete now (being an analog broadcast format) and TVs can do 60Hz, the problem is theoretically moot. (Though probably still a thing in reality.)
@Terxbor @dzuk the DVB standard, what every single way of receiving TV uses in the UK now (DVB-C for cable, DVB-S for satellite, and DVB-T for terrestrial aerials) is defined as 25p or 50i, with no option for any other framerate.
so every broadcast show still has to scale to 50hz, even if the TV's panel natively runs at 60hz (many LCDs sold in europe do natively run at 50 tho) even ones in HD, even tho the blurays will show the content in its native 24p or 30p/60i.
so, remnants still very very relevant
@dzuk @Terxbor funnily enough, this is a large part of netflix and amazon's success here – people prefer the 30fps stuff they serve, which don't have a UK-specific version, and the pacing just feels less rushed and tense and stuff.
at least with the people who know me, so i'm sure there's sample bias there
so it's basically just a more flexible standard by virtue of netflix having so many codec and resolution options, while DVB (or DVB..2? II? for HD) has to be a tight standard so every single box built will be able to receive it without having to do updates or anything
it seems like it won't rly stop, attempts to standardise on a worldwide frame rate never settle on 50 or 60
