babu.. FYI as per NASSCOM chennai is the second largest exporter of IT after bangalore .... actually as per the stat the IR growth rate in chennai is the highest.... "Now because of Karunanidhi policies Tamil Nadu which was one the leading state in south India few decades back is now far behind with other south Indian states." Do you know when anti-hindi agitations happened its during 1960s ... dont tell us that it has brought down the IT development of tamil nadu....
