These divestments and investments helped the Tata group shake off the slightly fusty image it had built up in the 1980s and make it fit for purpose in the modern world, according to Witzel. Indeed, today, the Tata groups most profitable company is information technology firm Tata Consultancy Services Ltd (TCS), which boasts around $10 billion (around Rs.54,700 crore) in revenue and serves customers around the world. I think the creation of the corporate brand was quite important. The Tata corporate brand is one of the worlds most valuable global brands because it harnesses the power of the whole group and creates a strong image in the minds of the stakeholders, Witzel added. Tata himself sees the re establishment of the group identity as one of his achievements. In the interview that was posted on the groups website, he said one of his most satisfying moments as chairman was the welding of the organization together in a more cohesive way than it had been in the past, that it was able to identify itself more as a group. And, even as some of these efforts to establish himself, improve the operational effectiveness of some companies, and reiterate a group identity were bearing fruit, Tata went out and made a big ticket global acquisition the Tetley group in 2000.
