After you’ve checked out the video, here are some things you can do to celebrate Messenger’s 10th anniversary with us:

• Visit our Messenger anniversary celebration site in the US or in the UK and download a special anniversary gift pack with free themes and emoticons.
• Send a Happy Anniversary IM to at least 10 of your friends and let them guess whose anniversary you’re celebrating (you can use a 10 Year Anniversary emoticon to make it a bit easier for them)
