Etisalat, the government-owned telecommunications provider, held a virtual monopoly over telecommunication services in Dubai prior to the establishment of other, smaller telecommunications companies such as Emirates Integrated Telecommunications Company (EITC—better known as Du) in 2006. Internet was introduced into the UAE (and therefore Dubai) in 1995. The network has an Internet bandwidth of 7.5 Gbit/s with capacity of 49 STM1 links. Dubai houses two of four Domain Name System (DNS) data centres in the country (DXBNIC1, DXBNIC2). Censorship is common in Dubai and used by the government to control content that it believes violates the cultural and political sensitivities of Emirates. Homosexuality, drugs, and the theory of evolution are generally considered taboo.
