On current move ICANN has started deleting outdated domain, they have already deleted .um tld, .um is now no more in use, this domain was for US minor outlying islands and the university of Southern California’s Information Science Institute which had grown tired for maintaining it. Another domain .su comes on the top of the list on deletion of outdated suffixes, however it is not easier for ICANN to remove .su as google still lists 3 million of .su sites though ICANN has started taking comments for deletion of such outdated domain.
