Creative Micro Designs (CMD) was founded by Doug Cotton and Mark Fellows in 1987. Today the company name is CMD Technology Group, not to be confused with (

The company started by developing and selling hardware peripherals for Commodore computers. The first products included a hardware floppy fast loader and the floppy OS JiffyDOS. At the close of C64 production by Commodore CMD bought the distribution rights of the OS GEOS from Berkeley Softworks.

In 2001 CMD discontinued selling and supporting Commodore products. From 2001 until 2009 distribution was taken over by Maurice Randall's company Click Here Software; Randall is the programmer of the GEOS upgrade "Wheels". Starting in 2006 posters to online C64 discussion forums commented on problems with distribution by Click Here Software.

Since 2010 the JiffyDOS product series has been sold by Jim Brain's company RETRO Innovations.
