Which game bundle originally included Portal?

Portal was originally included in The Orange Box. Valve released this compilation in 2007 for Windows, Xbox 360, and PlayStation 3, using it to introduce three new games alongside earlier Half-Life titles.

The package contained five major games: Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two, Team Fortress 2, and Portal. Portal was the smallest and most experimental of the new releases, while Team Fortress 2 was the long-awaited multiplayer sequel and Episode Two continued Gordon Freeman's story.

The bundle helped Portal reach a much larger audience than a short standalone puzzle game might have found. Its unexpected popularity turned it into the Orange Box's surprise favorite for many players. This question can cause confusion because Portal later received a standalone retail release in 2008, but The Orange Box was its original commercial home.
