On February 14, 2007, Valentine's Day, the Google doodle featured a chocolate-dipped strawberry that combined the second "g" and the "l" as its green stem. This design gave the appearance that the "l" was missing, thereby displaying "Googe".
In response to several speculations the Official Google Blog, responded: "When you look at the logos, you may worry that we forgot our name overnight, skipped a letter, or have decided that 'Googe' has a better ring to it. None of the above. I just know that those with true romance and poetry in their soul will see the subtlety immediately. And if you're feeling grouchy today, may I suggest eating a strawberry."
