History
The cards were developed by Olympus and Fujifilm, and introduced into the market in July 2002. Toshiba Corporation and Samsung Electronics manufacture the cards for Olympus and Fujifilm. xD cards are sold under other brands, including Kodak, SanDisk, PNY, and Lexar, but are not branded with the respective companies' logos, except for Kodak. Because of its higher cost and limited usage in products other than digital cameras, xD has lost ground to SD, which is broadly used by cellular phones, personal computers, digital audio players and most other digital camera manufacturers.
Olympus began to earnestly move away from the xD format with the release of the E-P1 camera, which supports only SD memory cards. As of Spring 2010, all new Olympus cameras announced at the 2010 Consumer Electronics Show and Photo Marketing Association International Trade Show can use SD cards. Note that this changeover to the SD card format has never been officially announced by Olympus corporation.
