Sony's created some iconic gadgets from the Walkman to the PlayStation. But not everything launched by the consumer electronics manufacturer is a success. Here's 10 products that didn't quite make it.
Launched with much fanfare at the E3 gaming expo in 2009, the PSP Go was supposed to be a major refresh for the PlayStation Portable. It did away with the UMD (Universal Media Disc) format used in previous PSPs in favour of a sleeker look, but that meant gamers couldn't play titles they already owned. And because it was more expensive than previous PSP models, many gamers saw no compelling reason to upgrade. A recent price cut may stimulate demand, but at this point the PSP Go rates as one of Sony's few gaming flops.
Not every product that fails does so because consumers aren't interested in it. Consider Sony's XEL-1, the world's first OLED TV. When it arrived in late 2007, it wowed everyone. The OLED screen produced images with deeper, brighter colours than LCD panels could generate, and it allowed Sony to make the 11in TV superthin. Most people who saw it wanted one - until they noticed the $2,000 (£1,200) price tag. To date, no manufacturer has succeeded in delivering larger OLED TVs. Sony pulled its version off the market earlier this year.
