In just a span of 5 years (2010-2015), Nokia’s domination of smartphone market has dwindled to the point of almost oblivion. It shows how a dominant tech company can fall from grace so quickly in the face of better and more advanced competitors. So who overtook Nokia? Apple and Samsung of course. Apple seems to have a strong market share in US, and European market. Samsung may have the biggest market share but Apple’s profit is many times that of its closest competitor.
