The Sims 1 (2000) had 7 DLC. The Sims 2 (2004) had 18 DLC. Halo 2 (2004) had several multiplayer map pack DLC. Doom 3 (2004) had at least one DLC. Star Wars Battlefront 1 (2004) & 2 (2005), KotOR (2003), and The Clone Wars (2002) all had DLC. Practically every sports game on the original Xbox had roster DLC.
I think DLC were more common than people remember, even if its not to the scale it is today.
