For most of the 1980s and early 1990s, analog joysticks were the predominant form of gaming controller for PCs, while console gaming controllers were mostly digital. This changed in 1996, when all three major consoles introduced an optional analog control. The Sony Dual Analog Controller had twin convex analog thumbsticks, the Sega Saturn 3D Control Pad had a single analog thumbstick, and the Nintendo 64 controller combined digital and analog controllers in a single body, starting a trend to have both an analog stick and a d-pad.
