I strongly believe that the .tv extension will be the second TLD just behind .com, that's why I started buying it since 2005.
I even thought by the time we are 40, the internet and the .tv extension will be combined into tranditional televisions, then we don't need to select a channel by clicking "numbers" on a remote control anymore. Instead, all we need to do is to type a .tv domain name into television, and we will see what we wanted to see.
