The Memory Stick is a removable flash memory card format launched by Sony in 1998. Sony exclusively used Memory Stick on its products in the 2000s such as digital cameras, digital camcorders, mobile phones, TV sets, PCs, digital audio players, and the Playstation Portable game console. The SD card, jointly developed by Toshiba, Panasonic, and SanDisk became widely popular among companies and soon became the most popular flash format – by November 2003 it held 42% market share in the United States, ahead of CompactFlash’s 26% and Memory Stick with 16%.
