DWDD stands for "De Wereld Draait Door," which is a popular talk show in the Netherlands. It's kind of like when you have your friends over, and you all sit around and talk about what happened that day, except it's on TV and lots of people watch it.
There is a host named Matthijs van Nieuwkerk, who talks with lots of different guests like musicians, actors, politicians, and even scientists. They talk about lots of different things like news, music, movies, and TV shows.
Lots of people really like watching DWDD because they learn new things and get to hear from interesting people. The show is on TV every weekday for an hour, so that's a lot of talking!
