A feature unique to the Wii is the console's wireless controller, the Wii Remote (or "Wii-mote"), which may be used as a handheld pointing device and can detect motion and rotation in three dimensions. The controller also contains a speaker and a rumbling device to provide sensory feedback. The console has a
stand-by feature entitled WiiConnect24, enabling it to receive messages and updates over the Internet while consuming very little electrical power
.
Nintendo unveiled the system under the Revolution code name in 2005 at its E3 press conference. Satoru Iwata, Nintendo's President, revealed a prototype of the system's game controller at the 2005 Tokyo Game Show during his keynote speech in September. Wii also boasted the longest line in E3 history, a
four hour wait to get into the booth with additional waiting time to play a game demo. The console is scheduled for release in the fourth quarter of 2006 with no more than four months difference between the first and last launching regions.
