Now is the time to watch Netflix's TUDUM. The biggest streaming service is giving a preview of its future plans to stay on top of the best streaming services.

It hasn't even started yet, and already the first news from TUDUM has come in: Netflix has announced that Season 4 of "Aggretsko" will be available this December!

In the age of virtual events, when conventions like San Diego Comic-Con have all but disappeared, a new way of sending out announcements has taken their place: the "Nintendo Directs" (game companies announce a large number of titles in rapid succession and stream them) that began in 2011. (streaming distribution), in which game companies announce a large number of titles in rapid succession.

But Netflix does everything a little differently, and even invented its own name for the event: "TUDUM." This spells out the first noise you hear when Netflix watches something on this service. And while Nintendo's live streaming presentations are not very long, Netflix spends a full three hours on all the big news.

And Netflix crams as many celebrities into TUDUM as it can fit into three hours. Everyone from Dwayne Johnson to Charlize Theron will be showing new work, as well as many big names like Idris Elba and Jason Bateman.

Watch the trailer here:
