The entire country of India is an IT company, composed of tinier IT companies. (baby IT companies, if you will) So technically, there is only one. If you are wondering how many sub(baby)-IT companies there are, there are too many to count. Also, too many to name any. They are like the mathematical theory of zero divided by zero. (see "what does zero divided by zero mean?" on answers.com) I hope that answers your question.
