ITC Ltd, an Indian conglomerate founded in 1910, has diversified from tobacco into several sectors including FMCG, hotels, and paper products, achieving significant growth and profitability. The company's strategic focus on leveraging internal competencies, acquisitions, and joint ventures has led to continuous success, with its stock price increasing over 1200% in the last decade. However, ITC remains heavily reliant on its cigarette business for profit, as observed during its diversification efforts.
