New Delhi: Internet-based businesses such as online advertising and e-commerce are slated to touch USD 100 billion size by 2015, a report by Economist Intelligence Unit has said.

"Even in India, where only 10 per cent of the population is online, 1.6 per cent of GDP is attributed to the rise of the Internet. This is expected to double by 2015 to be worth USD 100 billion --- the same size as the nation's healthcare industry today," the report said.

It added that one of the key factor that will drive the Internet economy in India is digital and mobile advertising.

The report 'Good to Grow: The Environment of Asia's Internet Business' said that at present, advertising revenue in India is at 7 per cent but out of the USD 410 million being spent online, 60 per cent goes to Google and Facebook, with only the remaining 40 per cent going to other online players.

The World Economic Forum's Network Readiness Index puts Singapore, Japan, Taiwan, South Korea and Hong Kong in the top 20 countries globally for the quality of their digital infrastructure but India, Thailand, Indonesia and the Philippines sit at the opposite end of the spectrum, it said.
