Google loves a good April Fool’s Day prank. Here is a list of some of the hoaxes that the company pulled in prior years:

2002

• Google, two years into its life, announced a new “MentalPlex” search technology that supposedly read the user’s mind to determine what the user wanted to search for, thus eliminating the step of actually typing in the search query. This always led to a page full of April Fool’s results.

2002

• Google reveals the technology behind its PageRank Systems—PigeonRank. Google touts the benefits of this cost-effective and efficient means of ranking pages and reassures readers that there is no animal cruelty involved in the process. The article makes many humorous references and puns based on computer terminology and how Google PageRank really works.

2004

• Fictitious job opportunities for a research center on the moon. Luna/X (a pun to Linux as well as a reference to both the Windows XP visual style and Mac OS X) is the name of a new operating system they claimed to have created for working at the research center.

2005

• Google Gulp, a fictitious drink, was announced by Google in 2005. According to the company, this beverage would optimize one’s use of the Google search engine by increasing the drinker’s intelligence. It was claimed this boost was achieved through real-time analysis of the user’s DNA and carefully tailored adjustments to neurotransmitters in the brain (a patented technology termed Auto-Drink). The drink was said to come in “4 great flavors”: Glutamate Grape (glutamic acid), Sugar-Free Radical (free radicals), Beta Carroty (beta carotene), and Sero-Tonic Water (serotonin).

This hoax was probably intended as a parody of Google’s invite-only email service called Gmail. Although ostensibly free, the company claimed the beverage could only be obtained by returning the cap of a Google Gulp bottle to a local grocery store: a causal loop. In the Google Gulp FAQ, Google replies to the observation “I mean, isn’t this whole invite-only thing kind of bogus?” by saying “Dude, it’s like you’ve never even heard of viral marketing.”

2006

• On April Fool’s Day 2006, Google Romance was announced on the main Google search page with the introduction, “Dating is a search problem. Solve it with Google Romance.” It pretends to offer a “Soulmate Search” to send users on a “Contextual Date”. A parody of online dating, it amusingly had a link for “those who generally favor the ‘throw enough stuff at the wall’ approach to online dating” to Post multiple profiles with a bulk upload file, you sleaze in addition to Post your Google Romance profile. Clicking on either of these gave an error page, which explained that it was an April Fool’s joke and included links to previous April Fool’s Jokes for nostalgia.

2007

• At about 10:00 PM Pacific time (where Google has its headquarters) on 30 March 2007, Google changed the login page for Gmail to announce a new service called Gmail Paper. The service offered to allow users of Google’s free webmail service to add e-mails to a “Paper Archive”, which Google would print (on “96% post-consumer organic soybean sputum”) and mail via traditional post. The service would be free, supported by bold, red advertisements printed on the back of the printed messages. Image attachments would also be printed on high-quality glossy paper, though MP3 and WAV files would not be printed. The page detailing more information about the service features photographs of Ian Spiro and Carrie Kemper, current employees of Google. Also featured are Product Marketing Managers of Gmail Anna-Christina Douglas, and Kevin Systrom.

• Google TiSP (short for Toilet Internet Service Provider) was a fictitious free broadband service supposedly released by Google. This service would make use of a standard toilet and sewage lines to provide free Internet connectivity at a speed of 8 Mbit/s (2 Mbit/s upload) (or up to 32 Mbit/s with a paid plan). The user would drop a weighted end of a long, Google-supplied fiber-optic cable in their toilet and flush it. Around 60 minutes later, the end would be recovered and connected to the Internet by a “Plumbing Hardware Dispatcher (PHD)”. The user would then connect their end to a Google-supplied wireless router and run the Google-supplied installation media on a Windows XP or Vista computer (“Mac and Linux support coming soon”). Alternatively, a user could request a professional installation, in which Google would deploy nanobots through the plumbing to complete the process. The free service would be supported by “discreet DNA sequencing” of “personal bodily output” to display online ads that relate to culinary preferences and personal health. Google also referenced the cola-and-Mentos reaction in their FAQ: “If you’re still experiencing problems, drop eight mints into the bowl and add a two-liter bottle of diet soda.” Also, look for delivery offered through the sewage system!

2008

• Google releases Adsense for conversations (http://adsense.blogspot.com/2008/04/introducing-adsense-for-conversations.html)

• The Blogger dashboard featured an announcement for Google Weblogs, or “GWeblogs,” or “Gblogs,” the next revolution in personal publishing. Features include algorithms putting your best content at the top of your blog (rather than publishing by reverse chronology), automatically populating your blog’s sidebar with the most relevant content, posting directly into Google search results for maximum visibility, blog headers refreshed with images from Google’s team of artists for anniversaries of a scientific achievement (similar to Google Doodle), and automatic content generation (‘Unsure of what to post about? Just click “I’m Feeling Lucky” and we’ll “take care” of the rest!’)

The announcement was followed by a link to a video tour of the product, which actually led to Tay Zonday’s cover of Rick Astley’s “Never Gonna Give You Up.” (See Rickrolling, below).

• Google launches Dajare in Japan (google.co.jp), with the mission of “organizing the world’s laughter.”

• Google announces gDay in Australia (http://www.google.com.au/intl/en/gday/press.html), a new beta search technology that will search web pages 24 hours before they are created.

• Gmail’s sign-in page and a banner at the top of each gmail inbox announced a new feature, called Gmail Custom Time, that would allow its users to “pre-date” their messages and choose to have the message appear as “read” or “unread”. The new feature uses the slogan “Be on time. Every time.”

Around 11:00 p.m. EST March 31, 2008, on the newer and older version of Gmail, but not in the basic HTML version, in the upper right corner, next to Settings, a link appeared labeled, “New! Gmail Custom Time”. The link led to a 404 error until April 1, when it led to the full Gmail Custom Time hoax page. Clicking any of the three links at the bottom of the page brought the user to a page stating that Gmail Custom time was, in fact, their April Fool’s day joke.

Google wrote that the new joke feature “utilizes an e-flux capacitor (a pun from the movie Back to the Future) to resolve issues of causality.” Fake testimonials are given by “beta users”; one example is, “I used to be an honest person; but now I don’t have to be. It’s just so much easier this way. I’ve gained a lot of productivity by not having to think about doing the ‘right’ thing.”

The feature only allows for ten pre-dated emails per year, claiming that any more “would cause people to lose faith in the accuracy of time, thus rendering the feature useless.”

• Google Book Search has a new section allowing users to “scratch and sniff” certain books. Users are asked to “…please place your nose near the monitor and click ‘Go’”, which then “loads odors”. When clicking on “Help”, users are redirected to a page in a book that describes the origins of April Fools’ Day.

• Google added the “I’m Feeling Lucky” button to its calendar feature. When you tried to create a new event, you were given the regular option of entering the correct details and hitting “Create Event,” and also the new option of “I’m Feeling Lucky” which would set you up with an evening date with, among others, Matt Damon, Eric Cartman, Tom Cruise, Jessica Alba, Pamela Anderson, Paris Hilton, Angelina Jolie, Britney Spears, Anna Kournikova, Johnny Depp, George W. Bush, or Lois Griffin.

• Google announces Google 사투리 번역 (Google dialect translation) for translating regional dialects of Korean to and from Standard Korean.

• A little easter egg was added to GoogleDocs, where a user can click the file menu and directly under new document is “New Airplane” which immediately opens a copy of a Google branded paper airplane. To reach the file menu, click the new menu, then “Document” then a new window opens.

• Google launches Manpower Search (谷歌人肉搜索) in China (google.cn). This new feature is powered by 25 million volunteers who do the searching around the clock. When the user entered a keyword, volunteers will search any possible answers from a mass of paper documents as well as online resources. The user is expected to get the search result within 32 seconds.

• Google changed the licenses on the Summer of Code (SoC) pages to all be “WTF Public License, Version 2″.

• Google announced plans to, on April 22, 2008 (Earth Day), shorten all conversations over Google Talk thereby reducing the energy required to transmit chats in an effort to reduce carbon output.

• Google launched their “Wake Up Kit” as a calendar notification option.

The ‘wake up’ notification uses several progressively more annoying alerts to wake you up. First it will send an SMS message to your phone. If that fails, more coercive means will be used. The kit includes an industrial-sized bucket and is designed to be connected to your water main for automatic filling. In addition, a bed-flipping device is included for forceful removal from your sleeping quarters.

• Google announces a joint project with the Virgin Group to establish a permanent human settlement on Mars (http://www.google.com/virgle/index.html). This operation has been named Project Virgle. The announcement includes videos of Richard Branson (founder of Virgin Group) as well as Larry Page and Sergey Brin (the founders of Google) on YouTube, talking about Virgle.  An “application” to join the settlement includes questions like “I am a world-class expert in” A. Physics, B. First Aid, C. Engineering, or D. Guitar Hero II. After you submit the application, the site notifies you that you are not fit for space, or that your application is fine and “all you have to do is submit your video” [as a response to their video on YouTube]. As a result, an open source Virgle group has been established, OpenVirgle.

• Google’s Orkut displayed its name as Yogurt.

• On April 1, 2008, all featured videos on the UK and Australian homepages, and later, all international homepages, of Google-owned YouTube linked to a video of Rick Astley’s song “Never Gonna Give You Up”, causing all users of the website who clicked on featured videos to be Rickrolled. This was the first year YouTube participated in Google’s April Fool’s day tradition.

What will Google come up with tomorrow?
