What year did Dungeons & Dragons come out?

While it feels like it's been with us since the time of the ancients, it turns out there was a time when Dungeons & Dragons didn't actually exist.

Whether it's informing basically all of Stranger Things, bringing us new movies to look forward to, or giving us a way to stay connected through the years and across borders, D&D is culturally probably the most important thing to have happened in the last few centuries.

But when did it first come out?
