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 colors than LCD panels could generate, and it allowed Sony to make the 11-inch TV superthin. Most people who saw it wanted one -- until they noticed the $2000 price tag. To date, no manufacturer has succeeded in delivering larger OLED TVs. Sony pulled its version off the market earlier this year.
