Toshiba Corporation (OTC: TOSBF) is a leading manufacturer of electronics, digital products, and social appliances. Toshiba is the world's second largest maker by market share, after South Korea's Samsung Electronics Co., of NAND flash memory chips and is a chip supplier for the iPhone. NAND memory chips are used in mobile phones, digital cameras, and laptop computers. Despite falling memory prices, Toshiba is counting on strong flash memory demand to continue lifting its overall earnings due to strong demand for smartphones.

Its diversified offerings means that Toshiba is involved in complex relationships with companies that are sometimes competitors and other times partners. Toshiba's semiconductor division co-developed the main processing and graphics chips used in Sony's advanced video game console, the PlayStation 3. On the other hand, Toshiba's digital products group co-invented the HD-DVD format, which lost the fierce battle with Sony's Blu-Ray format for dominance of the next generation media format.
