Tesco

Tesco plc is a UK-based international grocery and general merchandising retail chain. It is the largest British retailer by both global sales and domestic market share, and is the world's third-largest retailer, behind Wal-Mart of the United States and Carrefour of France.

Tesco now controls just over 30% of the grocery market in the UK, approximate to the combined market share of its closest rivals, Asda and Sainsbury's. In 2007, the supermarket chain announced over £2.55 billion in profits.

Originally specialising in food, it has diversified into areas such as discount clothes, consumer electronics, consumer financial services, selling and renting DVDs, compact discs and music downloads, Internet service, consumer telecoms, consumer health insurance, consumer dental plans and budget software. They are now entering into the housing market, with a self advertising website called Tesco Property Market.
