I've had good luck with trakt.tv to find new things. I usually just sync up what I watched with it with the SeriesGuide app, but it does have very basic "popular" lists in that. The trakt site is good for various lists and searches and you can see lists made by other users. SeriesGuide also let's me know when a new season of a show I've watched is coming out. The 2 pair week with each other. Trakt has it's own app pretty recently, but I haven't tried it.

I am looking for new things to watch at the moment which is what brought me here :)
Sometimes I look at pogdesign.co.uk/cat. I've used it for years and I'm surprised it's still around because I think it's rather unknown.
I see there are equivalent wikipedia pages for British and Japanese TV for the given year including Debuts. Presumably other countries are covered I just randomly checked for those. Thanks for the recommendation . I haven't got any useful methods to recommend sorry. I occasionally browse other / less known streaming platforms out of interest and sometimes find something different. Belonging to or browsing genre specific groups/subs/magazines etc can be good e.g scifi, documentaries, etc
I use a site called airdates.tv. I color code shows green if I definitely want to watch and yellow if shows Ill watch if there's nothing else to do. If I see a show I haven't heard of, there's a bunch of links when I click on the show to find out what it is.
