The cultures that tend to ship buggy software also tend to be the sort of cultures where the quality doesn't improve in response to a competitor however. But so far almost every software business has ultimately failed so being on top for a decade because you shipped some of the solution earlier works better. Customers are more than happy to buy exceptionally buggy software and games.
I wouldn't go that far. All the cases you cite are of products that definitely classify as substantially better than what they replaced.
Before Gmail took over the market from Hotmail there had been several other companies that failed due to only being slightly better.
Yes you can beat the "first mover", but doing so is hard and requires an almost revolutionizing better product.
Sure, but before that they generally make a lot more money than the second and third mover. When all is said and done, Atari and Yahoo did much better than Colecovision and Lycos.
The risk with being the first mover is that, having easily seen off competition from the second and third mover, you become complacent and stop moving.
Despite that, hotmail still exists.
While first mover doesn't guarantee success, it's certainly an illusion.
Early on I swapped from yahoo mail to gmail to hotmail because gmails spam filtering wasn’t good enough. Among my fiends Gmail really won on UI not space.
