Due August 1st, 2010 - We are bringing our celebration of the 25th birthday of the Blizzard® online and you are cordially invited to the party.

Operation Happy Birthday is one of our online initiatives celebrating the 25th birthday of one of the most recognized and beloved treats, the Blizzard. We are inviting our fans to record and submit a video clip (no longer than one minute) with your most original, creative or funny version of you, your family, your friends or your pet singing happy birthday to the Blizzard Treat.

Can’t sing? That’s okay!

You can also rap, rhyme, dance or play your favorite instrument. That’s only scratching the tip of the creativity iceberg. Be creative, be yourself, be original and have fun! Show us how creative you can be celebrating the Blizzard Treat’s birthday in a 60-second video. So get your friends, family, pets and office workers to join in the fun!

Videos will be judged on the following criteria:

1. Creativity
2. Originality
3. Adherence to theme and time limit
4. Amount of video page views generated – so remember to tell your family, friends, co-workers, teammates and neighbors to view your entry.
