Okay kiddo, let me explain what happened in 2007 in the world of machinima in a way you can understand.
Machinima is when people use video games to make movies or shows. In 2007, lots of cool things happened in the world of machinima.
First of all, a big website called Vimeo started allowing people to upload their machinima videos on their site, which made it easier for people to find and watch them.
Secondly, a game called Halo 3 came out and it had a feature that allowed players to record and share their gameplay, which made it really easy for people to make machinimas using that game.
Thirdly, a group of machinima creators called Rooster Teeth released a movie called "Red vs Blue: Reconstruction" which was really popular and won a bunch of awards. It was about two teams of soldiers fighting each other, but it was funny and had really cool action scenes.
Overall, 2007 was a big year for machinima and lots of people were making cool videos using video games.
