The line graph compares the percentage of mobile phone sales by three companies: Motorola, Nokia, and Sony Ericsson across a decade, from 1994 to 2004. Overall, the proportion of sales by three manufacturers fluctuated significantly throughout the given timeframe. In addition, the market share of Motorola was considerably higher during the first half of the period, after which it was overtaken by Nokia for the remainder of the period.
Upon closer examination, in 1994, Motorola dominated the mobile phone market, accounting for one-third of the total market share. However, in the following 6 years, its sales plummeted to about 15%, being overtaken by Nokia. From 2000 onwards, the figures for mobile phone sales rebounded slightly to approximately 17%, becoming the second-largest phone seller.
As far as Sony Ericsson is concerned, during the first half of the period, its sales share increased gradually to 15%, before dropping steadily to around 7% in 2003. In the final year, the manufacturer experienced a slow recovery to 10%, remaining the smallest mobile phone manufacturer.
In stark contrast, in the first four years, the sales of Nokia recorded a marginal fluctuation. In 1997, however, its market share surged to over 35%, surpassing Motorola and reaching its peak in 2002. In the last two years, the manufacturer underwent a noticeable decrease to 30%.
