The image to the left illustrates Samsung's market share in 2009 vs. 2010. As you can see, Samsung held only 4% of the market share in the smart phone industry in 2009 but made a huge leap in 2010 where they stole 23% of the market share. Samsung's success continued (as show on the last slide) into 2012 where their market share grew 6 more percent. This 6% growth was crucial and very impressive because iPhone released their iPhone 4s and iPhone 5 within 6 months of each other but was unsuccessful in stealing Samsung's market share.
Samsung's domination isn't only in the United States, its everywhere. The graph to the left shows the tablet market share Samsung holds in India. Samsung owns 56.2% of the market share! That means that more than half of every tablet sold in India is a Samsung.
