Google logo -- Valentine's Day

Yesterday was Valentine's Day Google released two doodle logos. first one is G XOgle, some people may ask what does "XO" mean? The answer is Hugs and kisses, also love and kisses.

The Oxford English Dictionary states that X is "used to represent a kiss, esp. in the subscription to a letter There is no general consensus on the origins of the O as a hug. The O could relate to the shape formed when two hands are crossed in a hug, forming a type of O. The 'X' may also refer to the pursing of the lips when kissing.

Similarly, written letters or greetings cards often include 'X' after a person's name or signature to indicate a kiss.

There is much debate on whether X's represent hugs or kisses. Some argue that X's represent kisses, but due to the "hugs and kisses" paradigm, some contend that 'X' is in fact lined up with the 'hug' and 'O' with the kiss. Also, arms crossing while hugging indicate an X while puckered lips form an O.

The second logo is a couple of happiness birds, who lean on each other.

Also you can see the previous year's Valentine's Day logos 2000 to 2008 here .
