If you’ve been on Google search today, you most definitely would have seen the birthday spinner doodle/game featured on the homepage or beside the search box if you’re on mobile.

While Google is known to feature new doodles regularly to celebrate notable people and events, this one is, however, special.

Google is celebrating its 19th birthday! Yes, you read that right, 19 years of answering almost every question you could possibly think of.

However, there’s some controversy surrounding the exact day that’s Google’s birthday, as the tech company has, in the past, celebrated its birthday on days other than the 27th. Google’s birthday has been marked on the 7th, the 8th, and the 25th, and only stuck with the 27th of September in 2002.

Also, it could be said that Google is 20 years-old, depending on where you’re counting from. If you use the date when Google.com domain was first registered, then Google would have turned 20 on 15th of September.

Date aside, it can be agreed that Google’s story over the years looks like the stuff of fairy tales. From its humble beginnings in a garage, Google has grown to become the most used search engine in the world, with over 4.5billion users in 160 countries.

Let’s take a stroll down memory lane to see Google started and how far it has come.

Google was founded in 1995 at Stanford University by Larry Page and Sergey Brin. Larry was considering Stanford for grad school and Sergey, who was a student there, was assigned to show him around. They soon became friends and by the following year, they struck a partnership.

Working from their dorm rooms, they built a search engine that used links to determine the importance of individual pages on the World Wide Web. They called this search engine Backrub.

Backrub was later renamed Google. The name was a play on the mathematical expression for the number 1 followed by 100 zeros and reflected Larry and Sergey’s mission “to organize the world’s information and make it universally accessible and useful.”

In August 1998, Sun co-founder Andy Bechtolsheim offered Google founders $100,000, and Google Inc. was officially born. With this investment, the founders were able to get a team which made the upgrade from the dorms to their first office: a garage in suburban Menlo Park, California, owned by Susan Wojcicki (employee #16 and now CEO of YouTube).

In the years that followed, the company expanded rapidly — hiring engineers, and building a sales team. Google outgrew the garage and eventually moved to its current headquarters (a.k.a.“The Googleplex”) in Mountain View, California.

Today, Google has more than 60,000 employees in 50 different countries and 3.5 billion searches per day. Google has also branched from just a search engine to making hundreds of products used by billions of people across the globe, from YouTube and Android to Smartbox and, of course, GMail.
