Lego is patented in its present form: Lego building blocks were developed over many years. The company that would come to be known as Lego was started in 1932 building wooden toys, and began building interlocking blocks in 1949. But it wasn't until 1958 when the design for the current interlocking block was patented. That same design is still used, and Lego pieces manufactured in 1958 will work with pieces built today.

First release of Dungeons and Dragons: Dungeons and Dragons (D&D) is a role playing game (RPG) originally developed by Gary Gygax and Dale Arneson. It developed from the epic scale of table top war gaming, but the story was brought down to the level of individual heroes. Although it relied heavily on the mechanics for combat and task resolution, story telling and character/player interaction was central to the game. Its success led to an explosion in RPG games. D&D is still available, now published by Wizard of the Coast and is in it's 5th edition.
The assigned date of its release is a bit of a conjecture based on anecdotal references.
