I think it's because they turned a website list into a 60 billion dollar company in about 5 years. And one investor in the early days was Masayoshi Son, and he was once the second richest person in the world in 1999.

And that advert in the film Inspector Gadget.

It's not worth a corporate biography book, I admit.

[Edit] And after the dotcom crash, their market cap (in 2006/2007) was just half of its peak, quite impressive. And they never chickened out and bought, say, Disney. They stuck to their guns.
