Established in 1919 in East London by Jack Cohen, this retail chain is now the largest in Britain and the third largest in the world. Tesco originally specialised in food and drink but has diversified into clothing, financial services, car insurance, dental plans, electronic equipment, music, internet services and telecoms. On the Tesco website visitors can purchase all the products and services that they offer in store from the comfort of their own home such as every day food essentials, alcohol, CDs, books, DVDs and have everything delivered direct to their door and they can also purchase services too including travel insurance, broadband, home insurance, dental insurance and much more.
