you can us a sort_by filter to sort your items by popularity for example. desc or asc. I use the same method to list movies by years, and yes you just had to switch movie and TV. I hope this will help. Maybe someone could tell more. But for now you have one answer ^{^}

@macarrão said:
Search movies/series by year and genre
Good afternoon gentlemen,
I want to get all the movies or series that were launched in X year, with X genre. Currently, i'm using this request:

https://api.themoviedb.org/3/discover/movie?api_key=myapikey&original_language="en"&primary_release_date.gte=1929-01-01&primary_release_date.lte=1929-12-31&with_genres=878

There is a small error in your Request.
The original language parameter must be
&with_original_language=
And not just
&original_language=
And I see you are specifying language with the quotes. "en"
It is not necessary. The 2-letter ISO language code is enough. en

But I have a few questions about it.
1- Using the /discover/ is correct?

Yes, it is the right tool.

For me, it seens that using discover, not all the movies are shown, only the famous ones.
What could I use to show ALL the movies without anykind of pre filter?

This is not true. Everyone is informed.
The answer limit is:
Maximum 20 items per page.
Maximum 500 pages
Maximum 10,000 items.

2- The filter by year is correct? In the example, i'm trying to search for movies from 1929, but i'm not really sure if that works.

Yes, the filter for the period is correct.
However, as you want each year separate then you can use the filter for year.
&primary_release_year=

https://api.themoviedb.org/3/discover/movie?api_key=THE_KEY&language=en-US&sort_by=primary_release_date.asc&with_original_language=en&primary_release_year=1929 

This method you used is valid for a period longer than 1 year, or if it goes from one year to another year.

3- To search for tv series instead of movies, I just need to change the movie? to ** tv?** right?

Wrong. Date filter names are different.
first_air_date_year, first_air_date.lte, first_air_date.gte

Good morning,

Everything worked! Now I have a perfect request for my movies and series.

Thank you very much CubWolf, and ticao2, I really appreciate it.

Have a nice week.
