Though India’s top six IT companies accounted for 1.9 per cent of the total $672 billion IT services market in 2006, they are growing at a higher rate than their bigger global counterparts, a study reported. A study by research firm Gartner stated that six India's IT service providers — TCS, Infosys, Wipro, Cognizant, Satyam, and HCL Technologies — accounted for 1.9 per cent of the total $ 672 billion IT services market in 2006, compared to 0.5 per cent of the $554 billion IT services market in 2001.

Despite their relatively smaller size, the top six India's IT service providers are making significant strides to challenge the market share leaders’ positions by continuing to show strong annual revenue growth far exceeding the market norm.

The average annual growth rate of the SWITCH companies was 42.4 per cent in 2006, compared with a 4.3 per cent growth of the market leaders during the same period.
