The Hindu : Ratan Tata to function as non-executive chairman

MUMBAI DEC. 28. Ratan Tata, who turned 65 today, would now function as non-executive chairman of the Tata group. The board of directors has already given the nod to Mr. Tata continuing as non-executive head of the group with effect from tomorrow

Mr. Tata started as his career as executive chairman in 1991 but drew the outline of the Tata business in 1980 much before he was assigned as chief. Lets hope this is not the sunset of the great businessman and his reign.
A lot of business schools make a case study on Mr. Tata looking at him as a powerhouse of business ethics and originality of ideas as a entrepreneur.
