Last week, Google changed its search engine logo - one of the most recognisable designs - to depict a flying saucer pulling away the second "O" in Google with a tractor beam.
As expected, this rather significant move by the world's largest search engine quickly became a phenomenon on its own with some theories suggesting that Google might have made contact with aliens (or have used alien technologies or are in fact aliens themselves).
Google then went on to offer a precious clue on its official Twitter page, with the message "1.12.12 18.104.22.168 15 1.18.5 22.214.171.124.14.7 20.15 21.19", which translates into “All your O are belong to us” once you substitute the numbers with the corresponding letters of the alphabet.
It turned out that this grammatically incorrect phrase comes from a "Japanese video game of the 1980s, Zero Wing" and was once a meme before the internet really took off.
Google was actually celebrating the 20th anniversary of the game which was launched back in 1989. The game is a side-scrolling shoot 'em up arcade game (remember those?) developed by Toaplan and published by Taito in Japan.
So either Google senior management is either very fond of this game (and Google employees spend a lot of time on it) or there's something else going on.
How popular was the Zero Wing Page a few days ago? Well, according to WikiRank website which ranks popular terms on Wikipedia, the Zero Wing Wikipedia page was viewed on average 27 times per day. We'll get you an update by next week.
Will there be a conspiracy theory surrounding the true reasons why Google choose to celebrate the 20th birthday of Zero Wing. Google reached its 11th year on the 4th of September. Zero Wing came out on the 6th of September 1989, nine year before Google was launched.
