Tesco started as a small market stall in 1919 and has since grown to become a large international retailer. It opened its first store in 1929 and continued expanding in London through the 1930s. In the following decades, Tesco introduced various store formats and expanded its product range. It now operates over 3,400 stores across several countries. Tesco uses strategies like competitive pricing, a loyalty program, and various store formats to target different customer segments in both domestic and global markets. Adapting strategies to local conditions and customer needs is important for Tesco's international expansion.
