Satyam Computers was a major Indian IT services company before the 2009 fraud scandal. The question appears to be asking about 'Satyam Computers (Old)' - referring to the company before its rebranding as Mahindra Satyam. WIPRO, Infosys, and TCS are other prominent Indian IT companies that remain active, while Satyam was the one that experienced the major corporate fraud and subsequent acquisition.
