Montevideo is the heartland of retailing in Uruguay. The city has become the principal centre of business and real estate, including many expensive buildings and modern towers for residences and offices, surrounded by extensive green spaces. In 1985, the first shopping centre in Rio de la Plata, Montevideo Shopping was built. In 1994, with building of three more shopping complexes such as the Shopping Tres Cruces, Portones Shopping, and Punta Carretas Shopping, the business map of the city changed dramatically. The creation of shopping complexes brought a major change in the habits of the people of Montevideo. Global firms such as McDonald's and Burger King etc. are firmly established in Montevideo.

Jehovah's Witnesses believe their religion is a restoration of first-century Christianity. Doctrines of Jehovah's Witnesses are established by the Governing Body, which assumes responsibility for interpreting and applying scripture. The Governing Body does not issue any single, comprehensive "statement of faith", but prefers to express its doctrinal position in a variety of ways through publications published by the Watch Tower Society. Their publications teach that doctrinal changes and refinements result from a process of progressive revelation, in which God gradually reveals his will and purpose, and that such enlightenment or "new light" results from the application of reason and study, the guidance of the holy spirit, and direction from Jesus Christ and angels. The Society also teaches that members of the Governing Body are helped by the holy spirit to discern "deep truths", which are then considered by the entire Governing Body before it makes doctrinal decisions. The religion's leadership, while disclaiming divine inspiration and infallibility, is said to provide "divine guidance" through its teachings described as "based on God's Word thus ... not from men, but from Jehovah."
