Digital Equipment Corporation
I had family that worked for DEC so I would get my hands on some of the company swag, on occasion. I always felt a bit dissatisfied with the logo/wordmark so I kept a redesign simple with some curves and lines with a wordmark.
D + curves + lines = Digital
A bit about Digital:
(from Wikipedia)
Digital Equipment Corporation, also known as DEC and using the trademark Digital, was a major American company in the computer industry from the 1950s to the 1990s.
DEC was a leading vendor of computer systems, including computers, software, and peripherals. Their PDP and successor VAX products were the most successful of all minicomputers in terms of sales.
DEC was acquired in June 1998 by Compaq, in what was at that time the largest merger in the history of the computer industry. At the time, Compaq was focused on the enterprise market and had recently purchased several other large vendors. DEC was a major player overseas where Compaq had less presence. However, Compaq had little idea what to do with its acquisitions, and soon found itself in financial difficulty of its own. The company subsequently merged with Hewlett-Packard (HP) in May 2002. As of 2007 some of DEC's product lines were still produced under the HP name.
