Was Steve Jobs a monopolist or not?

Steve Jobs the co-founder, chairman, and chief executive officer of ‘Apple’ is a monopolist in my point of view. He was a pioneer of personal computer revolution which was through his technological determinism, critical studies and his theories because when so many product were manufactured with high competition for profit and to make their product a monopoly with almost similar configurations, with little variation and slight advancement in products. Steve Job’s product the APPLE stood out with a different OS the ‘MAC’. He was the one who brought the computer revolution. Nobody lends their ear to know about the barriers of entry that he had in order to become a monopoly. He also had economical support which helped him a lot. It is not just his economy but also the political economy, the standard of living of people which made his product reach the top in global market which in turn is of highest usage in various societies and culture. Thus he became the monopolist of the 21^st century with his product Apple.
