What happened to clan match in games?

I remember playing Halo 2 with a clan of my friends and being matched up with other clans. Mr friends and I learned how to work together as a team and got to earn a ranking together that we shared. Why have games stoped promoting clan match. I would love to see a game make it easy for players to organize clans and get matched up against other clans. It was nice to see this feature in COD 4 but how about Gears of War and Halo 3? Please developers, support clan match.

To be honest, it's sort of died off when people realized that playing with your friends is funner.
