Delegation is a term that, in the Domain Name industry, refers to the process of entering a new Top Level Domain into the Root Zone of the Internet. The Root Zone is the authoritative database for the Internet, and entering a new TLD finalizes the process of making the TLD "live" on the web. It is a process that is facilitated by ICANN and IANA.
New gTLD Program
During ICANN's expansion round that opened for applications in 2012, 1,930 applications were received for new gTLDs. By 23 October 2013, the first 4 TLDs from this program were delegated to the Root Zone.
