Naturally, national holidays get the same treatment. Mostly.
Web surfers landing on the Google North American home page on Memorial Day, 2014, would never know a national holiday is taking place all across the United States, since the standard search box stares out with not even a mention of a day centered on the idea of remembering stuff.
A quick look at the Google Doodle Archive shows that the last doodle celebrated Rachel Carson's 107th birthday and that, over the last few months alone, topics and figures as arcane as Rubik's Cube, Giambattista Tiepolo and the 230th anniversary of Prague existence as a single capital city were worthy of the honor.
And, oh yeah, the great "Holiday Series" debacle of 2013, which utterly ignored the word Christmas. Still, Google managed to rebound by New Year's Day. But, that one's kind of a no-brainer.
Google has been struggling with the Memorial Day Google Doodle issue for at least 6 years now, as evidenced by this reply to a query about the lack of a Memorial Day Google Doodle way back in 2008.
"Thank you for your note. We understand your interest in seeing a Memorial Day Google logo. If we were to commemorate this holiday, we’d want to express reverence; however, as Google’s special logos tend to be lighthearted in nature, this would be a particularly challenging design.
We wouldn’t want to create a graphic that could be interpreted as disrespectful in any way.
We have a long list of holidays that we’d like to celebrate in the future. We have to balance this rotating calendar with the need to maintain the consistency of the Google homepage. We really appreciate your feedback regarding the Google logo, and please be assured that we’re actively pursuing ways in which we can acknowledge Memorial Day and other such occasions in the future
Regards, The Google Team"
It's been six years. At the very least, put up an American Flag.
It doesn't even have to wave...
