Facebook's git repo is 54GB
Although this is large for a company that deals mostly in web-based projects, it's nothing compared to repository sizes in game development.<p>Usually game assets are in one repository (including compiled binaries) and code in another. The repository containing the game itself can grow to hundreds of gigabytes in size due to tracking revision history on art assets (models, movies, textures, animation data, etc).<p>I wouldn't doubt there's some larger commercial game projects that have repository sizes exceeding 1TB.
