Innovate or die. Blockbuster Video failed to do so by deciding not to move on to streaming video services. The writing was on the wall but nobody at Blockbuster reacted. Adios blockbuster.

Woolworths didn't innovate either and they failed to spot that their shoppers didn't even know why they need to go to their local Woolworths store - as you could get everything they sold from somewhere else - and in a nicer shopping environment. 

In short neither Blockbuster or Yahoo! innovated and neither have a 'hero' product.

As for Yahoo! - I have no idea why I would ever need to visit their website. 

Does anyone else?
