2010 - present
For the past 7 years, the manufacturers' challenge has focused on developing devices with a battery that lasts longer and with an elegant design that is light and thin.
In addition, Android technology has been in the north of many to allow the download of the most popular mobile applications on the market.
From the point of view of content producers in the world, there has also been a race to develop products that can be consumed from various devices, especially smartphones, as this connection mode today accounts for 75% of web traffic.
