Really inspiring and academic touch on Toshiba HD_DVD failure, supported by well-organized analysis from technological and economical perspectives with concise charts and complementary videos. As is mentioned, the failure is mainly attributed to its missteps in marketing strategy. It is truly a lesson for innovative products. One point might be worthy of discussion that HD-DVD is more incremental innovation than disruptive one given that it was developed, or to be exact, upgraded from a existing technology. I wont say it was a complete failure either because it was produced and marketed to the global markets. Or it might be a failure to some extent, for Toshiba in particular, its lifecycle was shorter than it was forecast. Yet it was unavoidable in the fast-changing and competing electronics world. Thanks for your logical work.
