Google have always flexed their creative sides when it comes to their own logo. You will often see the Google homepage feature a themed logo that represents either something that is happening that day, or to celebrate the anniversary of an event.
Today, however, Google have extended this to their YouTube arm.
Taking place tonight is Superbowl XLIII (43 for the non-Romans) between the American Football Conference champions "Pittsburgh Steelers" and the National Football Conference champions "Arizona Cardinals".
To mark the day of this event, YouTube have added a lovely little American football to their logo. Nice!
