The Verge has a profile article of Les Seules, the famous all women CS team.

”Les Seules was one of the first women’s Counter-Strike teams — actually one of the first Counter-Strike teams at all — to get noticed outside of the gaming world.”

They became a team only because there were no other teams for them to join in 2004. They finished 4th in their first Electronic Sports World Championship.
