488k is the number of posts, they have 19k followers. Pretty great news still tho

Also, you might want to take a look at https://zdf.social/@ZDF and https://ard.social/

ZDF and ARD are the two biggest broadcasters in Germany, and they both have their own ActivityPub (Mastodon) server.

In case you needed some extra convincing that other large mainstream news organisations also have realised that this is actually a good idea that makes sense ;)

A big news org from France is also on Mastodon with like 50k followers, but I cannot remember the name right now
