Worldwide semiconductor revenue totalled $333.7 billion (€307 billion) in 2015, a 1.9 per cent decrease from 2014 revenue of $340.3 billion, according to preliminary results by Gartner. Combined revenue of the top 25 semiconductor vendors increased 0.2 per cent, which was more than the overall industry's growth. The top 25 vendors accounted for 73.2 per cent of total market revenue, up from 71.7 per cent in 2014. The research company said weaker demand for key electronic equipment was partly to blame for the decline in the market in 2015. Other factors included the strong dollar: in the Eurozone, for example, the sales prices of mobile phones or PCs increased in local currency, as many of the components are priced in U.S. dollars.
