Where do you look to see what new shows are coming up, and what has debuted recently?
I used to use the /r/television sidebar but it isn't very comprehensive. More recently I've been using Wikipedia's 2023 in American Television page, specifically the debuts page, which is good. Some other countries have their own pages, such as South Korea.
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 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.
