The Thumb Economy
Below is the common technologies used in everyday life including the number of years they have been available to consumers and the world wide usage.
In just 35 years - roughly the same amount of time as the PC and nearly one-fourth that of the landline phone - mobile phone penetration has surpassed the PC and landline phone combined reaching over 2.7 Billion and bringing in the age of the thumb economy. The mobile economy has been growing so big that there will be more smartphones than PCs to be sold by 2011 and the mobile advertising market will be worth $11 Billion (£6.8 Billion) globally by 2011.
