JoshuaInNippon writes "In a brief press release buried within Sony Japan's website, the company announced that it would be ending sales of the classic 3.5-inch diskette in the country in March 2011. Sony introduced the size to the world in 1981, and it saw its heyday in the 1990s. Sony has been one of the last major manufacturers to continue shipments of the disk type it helped develop, but had ended most worldwide sales in March of this year. The company's production of the 3.5-inch floppy ceased in 2009. Sony noted demand, or lack thereof, as the reason. The company's withdrawal is one of the final acts in the slow death of the floppy era."
