The diagram we see illustrates the percentage of phones sold by different companies from 2000 to 2010. For this amound of time companies made lot’s of changes. Let’s see into.
Some made a big step upward among them are companies like iphone , Sansung and Redmi. Other felt a crusial fail, like Artel. Also there is one to not make any difference, like Huawey.
If we will look at the chart more closely it is noticable that iphone and Samsung made the biggest way up during that time. Since 2000 both of then increased their profit in three times. Before 2007 Samsung was close behind and that year they made almost same amount of sales. Well iphone is the only company to have the most stable path without any dramatical changes. Compared to two previous Redmi did a little worse but at 2003 sharply increased and now goes aling up with iphone. Artel is the company to feel the biggest fall in sales. Even though it started with the best ones. At 2010 It goes almost at the same level with Huawey. The only company to have the profit they had at the begining with only little fluctuation during 10 years.
The companies to have the biggest increas and decrease are iphone and Artel. iphone is finishig 2010 with the same level of Artel starting it and Artel is finishing the same year with profit that is lower than the profit iphone made at the 2000. These are the most signicant changes to appear.
