It s multiple areas that indicate success or failure and they will differ somewhat w each company - But the basics are : financial performance, market share and investor expectations
Merely making a profit is probably not enough for any of them to be considered a success- if MSFT loses a bunch of market share but makes a small or moderate profit ( this generation) they will prob consider it a failure - if Nintendo loses a bunch of market share AND makes significantly less money than they did on the Wii it will prob be considered a failure
