I got an email from Google with a thank you note and link to this video. I can't determine if the 'thanks to you...' is referring to me as a (one time) advertiser or as a regular Google user.

Edit (more clarity):

Here is the actual email from Google:

Dear ,

Thanks to you, this holiday season Google is able to donate $20 million to charitable organizations around the world. They in turn will help improve the lives of over 50 million people. Click here to see how.

Thank you for being a part of what Google is today. All this is possible because of you.

Have a wonderful holiday.

Google

Note that my name was not included in the email. I'm guessing they're missing a record on me.
