Even worse for IBM, just about every advance it made in the PS/2 ended up being matched (or cloned) and then surpassed by the clone vendors. Sales of the PS/2 slipped dramatically through the rest of the 1980s, and the PS/2 line became an embarrassing public disaster for IBM.
By 1990, it was abundantly clear that IBM no longer guided the PC-compatible market. And in 1994, Compaq replaced IBM as the number one PC vendor in the United States.
IBM stuck with the PC market until 2004, when it sold its PC division to Lenovo. By that time IBM had scored a few more consumer PC innovations with graphics standards and portable computers (especially with the ThinkPad line), but none of its machines after the PS/2 would have the same impact as those it released in the early and mid-1980s.
