Created in 1884, Colombian telecoms operator ETB was for many years developed as a local telephone company. It subsequently added data and internet services to its portfolio of local phone and long distance services. ETB is now an associate of Colombia Móvil, a mobile phone company operating under the brand name Ola. Bogotá's municipal government has a majority stake in ETB.
