In 50Hz regions, almost all catch-up TV services will be 25p (BBC iPlayer includes 50p stuff), as will the streaming pay services of major TV platform operators (NowTV, ViaPlay, Cmore etc.), most DVDs released in 50Hz regions will be mastered 50i containing either 50Hz or 25Hz original content, and a significant number of TV series released on Blu-ray will also be mastered 50i containing 25p sources (The Blu-ray standard doesn't allow 25p native mastering).
There are some European TV series shot 25p but released 24p (as a "PAL slow down"), mainly to allow the same mastering for 50 and 60Hz regions, but they are the minority.
Anyone running a PVR back-end in a 50Hz region will need 50Hz compatibility for 50Hz Live / Recorded TV, as will any off-air recordings distributed via alternative means.
Netflix also includes a significant amount of 25p content (at least in Europe). The Crown is a notable 25p production, as are most shows produced as co-productions with 50Hz broadcasters, and most shows acquired from 50Hz broadcasters. AIUI Amazon have also switched from 23.976 to 25p for series 2 of The Grand Tour. Having automatic frame rate switching on Amazon and Netflix is one reason I prefer the ATV 4K, Roku Streaming Stick+ or my Sony Blu-ray player for watching Netflix and Amazon - as these three platforms all automatically switch frame rates on Amazon and Netflix if you want them to. (Many solutions - including some Smart TV apps - appear to run at a fixed frame rate...)
