Dude . The figure is about IT exports not the size of IT industry
Sorry!
Correction : In 2008 the following figure from the same web site - should pertain to 2006-2007 - was reported :
Estimated Total IT Industry Export Revenue : US$ 1.4 Billion.
As such the present Total IT Industry Export Revenue for 2010-2011 could be well over US$ 5 Billion.
By 2020it should cross US$ 20 Billion.
