Time out! Sideout?

Hey, since when did the rules of volleyball change - the rules I learned in gym class, er... P.E. - about the basics of keeping score? Now either team scores a point on the play regardless of which team is serving. When did this happen? What happen to only being able to score when you were serving?! Does this apply to all volleyball, or just international play? The beach volleyball still plays by the old rules, right? NBC really needs to elaborate on this instead of showing Michael Phelps for the gazillionth time.
