50 years ago today, John F. Kennedy gave his famous inaugural address. It was January 20, 1961 where John F. Kennedy was sworn in as the 35th president of the United States of America. It was the day where he gave his famous inaugural address and it is the inaugural address that Google used to design the Google logo found on Google.com.
Here is a picture of the logo and as you can see, Google design the logos from the words from his speech. In addition, Google incorporated their middle G, made up of the words of his speech, as a picture of John F. Kennedy.
As I mentioned at the Search Engine Roundtable, the first result for the query Google takes you to after clicking on the logo takes you to a page that has added an intermediate page to monetize the query. It appears this site noticed the traffic spike, set up a page with Google AdSense ads and then took users to the final destination page after waiting X seconds or clicking on a link. This is not something Google condones, I do wonder how long that page will last.
Also, Google has two other logos on different Google properties.
They have a special logo on Google Japan for Kenjiro Takayanagi, the inventor of the Television. They also have a special log on Google Israel for the Tu Bishvat holiday, which celebrates trees. Here are those logos:
