a while ago I've red a very good book about this phenomena. \nit called- "Built to Last: Successful Habits of Visionary Companies" by James C. Collins, Jerry I. Porras \n\nthey picked only companies that have lasted more then 50 years and tried to point out the reason for succeeding such a long time. I recommend it there is a lot to learn in it
why some companies have survived for more then 50 years while others have failed only after 5?   why is that ?
