Serial and parallel devices died off pretty quickly though the ports lived on for various reasons. PS/2 keyboard and mice endured a good while longer. I've only seen the joystick port appear on sound cards, which themselves are pretty much dead, and the AT connector was all but extinct by the mid 1990s. New motherboards seem to fall into two camps: Legacy ports of all flavours, or ridiculous numbers of USB 3.0 ports. I saw one recently with 12 USB3.0 connectors on the back.
