Rob Burgess, formerly a senior vice president at Silicon Graphics, will succeed Colligan, but the position of CEO at the company will be phased out. Burgess ran the Alias/Wavefront software subsidiary at SGI.
Company officials said Colligan will continue to be active in the company, concentrating on product development and sales and distribution, while Burgess will run day-to-day operations.
Macromedia (MACR) has seen its stock slide recently as sales have faltered.
Colligan is on the board of directors of CNET: the Computer Network.
