to start with, a year before the first iphone was released, lg had introduced a full touchscreen phone. even that was not the first, though. the world's first touchscreen phone was ibm's simon, which was released in 1992. and touchscreen technology even predates the simon. the first touchscreen device was a tablet made by e.a. johnson in 1965 that was used by air traffic controllers until 1995. bent stumpe and frank beck made the first capacitive touchscreen in the early '70s. unlike johnson's tablet, it could not be pressed with the fingers. instead, it required a stylus. in 1971, samuel hurst developed the first resistive touchscreen, which he called the "elograph." it responded to the fingers as well as a stylus. in 1985, hp invented the world's first touchscreen computer, called the hp-150. in 1993, apple also released its first touchscreen device—the newton personal digital assistant. the product was a flop, recording low sales.
