Technology giants: How the mighty have fallen

Digital Equipment Corporation

The recent death of Digital Equipment Corporation's founder Ken Olsen is a reminder that getting to the top of the tech world isn't easy but staying there is even harder. ZDNet UK's David Meyer takes a look back at 10 firms that were once leaders in the field but let technology pass them by.

Digital Equipment Corporation (DEC)
DEC's PDP-8 may not look so small now, but its relatively compact size made it a bestseller in the mid-1960s — the company sold 50,000 of its 'minicomputer', which was a record-breaker at the time. DEC became the largest private employer in the state of Massachusetts.

In the late 1970s, the company's VAX-11 32-bit minicomputer served as a rival to IBM's mainframes. However, a decade later saw the rise of the 32-bit microcomputer, and Digital's products lost their cachet. Its 1998 merger with Compaq was the biggest in the history of the IT industry. Four years later, Compaq itself merged with HP, leaving the DEC/Digital brand as little more than a memory.
