Firms like Hindustan Unilever already entered the mobile ad market by sending out text messages.

“Now other companies are following suit. The high level of mobile penetration provides immense opportunities for advertisers,'' said Padamsee, the Business Line reported.

Piyush Pandey, executive chairman of Ogilvy and Mather, pointed out that companies might have to customise advertising and make it into local dialects, so as to reach a greater number of rural citizens, according to the Business Line.

“We need to utilise the native intelligence and involve people from the local areas for such campaigns to get the best possible advantage of local knowledge,'' said Pandey.

According to Business Line, there is a potential for growth in rural parts of India if the right advertising tools are used.
