ICANN is the organization authorized to delegate Generic TLDs (gTLDs)
New gTLDs are registered through ICANN based on proposals that are submitted to ICANN during specific application periods. Applications received during these rounds are evaluated against previously-published criteria, and those applicants who are successful become the Registrant of a new gTLD. The criteria and conditions to register gTLDs are subjected to change. The fee to register a gTLD will be set at a level which enables the full recovery of costs associated with ICANN. You can find more information on this process at http://www.icann.org/topics/gtld-strategy-area.html.

IANA is the organization authorized to delegate Country Code TLDs (ccTLDs)
Two-character TLDs are reserved as country code identifiers under ISO 3166. In determining whether a new ccTLD should be created, the IANA follows the ISO 3166-1 list as published by the ISO 3166 Maintenance Agency. The appointment of a ccTLD manager is done in consultation with the participating country and ICANN. The selection of the ISO 3166-1 list as a basis for ccTLDs was made with the knowledge that ISO has a politically neutral procedure for determining which entities should be and should not be on that list.
