Tesco was founded in 1919 and has since grown to operate in 12 countries with over 530,000 employees. It faces competitive pressures from lower-priced rivals like Aldi and Lidl that are attracting customers. Tesco also had profits overstated by £250 million, damaging trust in management. While the economy remains weak, Tesco uses market trends effectively by changing its clothing line. It has a competitive advantage through home delivery and an online retail presence, allowing lower prices through reduced store costs. Location choices consider regulations, population size, and rental costs.
