A recently featured Search Engine Watch Forums thread named Yahoo Moves To Trademark Y.com shows hows Yahoo! will be gaining rights to Y.com soon. Msgraph, wrote in the thread;
1.) Some miraculous deal was reached because Yahoo was able to pulls some strings and will therefore be given Y.com in the near future. 2.) Yahoo is just covering some extra bases to prevent anyone else from attempting to trademark Y.com. Simply because they have Y! trademarked, and since IANA may never release Y.com or any other single-character domains, Yahoo is just going to take their chance on trademarking it. Or if IANA ever releases these domains, Yahoo may attempt to stake their claim on Y.com through the trademark.
