Rio is an important financial centre, second only to São Paulo in volume of business. Its securities market, although declining in significance relative to São Paulo, is still of major importance. Recent decades have seen a sharp transformation in its economic profile, which is becoming more and more one of a major national hub of services and businesses. The city is the headquarters of large telecom companies, such as Intelig, Oi and Embratel. Major Brazilian entertainment and media organizations are based in Rio de Janeiro like Organizações Globo and also some of Brazil's major newspapers: "Jornal do Brasil", "O Dia", and "Business Rio".
