After the initial three waves of generic top level domain creation (beginning in 1985 with the original seven, and then in 2000 with the creation of several more gtlds, including .info, .biz, and .pro and a third wave in the early 2000s which included .mobi, .tel and .asia), there was still a demand for additional generic top level domains. In 2011 the body responsible for administering the Internet naming system, ICANN, opened up the naming system, allowing for hundreds of new generic top level domains. These ranged from city names (such as .nyc and .melbourne) to more generic extensions (such as .store and .site).
