Source-derived summary

Tesco plc () is a British multinational groceries and general merchandise retailer headquartered in the United Kingdom at its head offices in Welwyn Garden City, England. The company was founded by Sir Jack Cohen in Hackney, London, in 1919. In 2023, it was the 15th largest retailer in the world by revenue. It is the market leader of groceries in the UK (where it has a market share of around 28.4%). Tesco also has stores in the Czech Republic, Ireland, Slovakia, the Isle of Man and Hungary.

Since the 1960s, Tesco has diversified into areas such as the retailing of books, clothing, electronics, furniture, toys, petrol, software, financial services, telecommunications and internet services. In the 1990s, Tesco re-positioned itself from being a downmarket high-volume low-cost retailer, attempting to attract a range of social groups with its low-cost "Tesco Value" range (launched 1993) and premium "Tesco Finest" range.

Tesco is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.

History

Origins

Jack Cohen, the son of Jewish migrants from Poland, founded Tesco in 1919 when he began to sell war-surplus groceries from a stall at Well Street Market, Hackney, in the East End of London. The Tesco brand first appeared in 1924.

Editorial summary

The public source identifies “Tesco” as british multinational retailer. This brief keeps that definition visible, then builds a research path around Tesco, British and multinational.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1919, 2023, 1993, 1924—that can be checked directly. The linked authority record independently contributes the date 1919. Its value is orientation rather than verdict, with Tesco, British and multinational providing the first useful test.
Editorial analysis

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
