GOOGLE  has created some very impressive milestones of its time and continues to grow rapidly every day.  It all started when Larry Page and Sergey Brin met in Stanford. Larry was 22 and a graduate of University of Michigan was there, considering attending the school. Sergey, who was 21, was there to show him around.

Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in California.

While conventional search engines ranked results by counting how many times the search terms appeared on the page, the two theorized about a better system that analyzed the relationships between websites.They called this new technology PAGE RANK.


PageRank is a link analysis algorithm, named after Larry Page and used by the Google Internet search engine. PageRank is a probability distribution used to represent the likelihood that a person randomly clicking on links will arrive at any particular page. PageRank can be calculated for collections of documents of any size. It is assumed in several research papers that the distribution is evenly divided among all documents in the collection at the beginning of the computational process. The PageRank computations require several passes, called “iterations”, through the collection to adjust approximate PageRank values to more closely reflect the theoretical true value. A 0.5 probability is commonly expressed as a “50% chance” of something happening. Hence, a PageRank of 0.5 means there is a 50% chance that a person clicking on a random link will be directed to the document with the 0.5 PageRank.

Websites are ranked just like movies. Some people watch movies that are recommended by friends and family. Others may only watch movies that are highly recommended by a movie critic.Like websites, when someone gives good reviews about a movie, naturally the movie will be ‘ranked’ higher, correct?

Your websites are just like that. When another website ‘recommends’ you by linking to you, you get a vote. The more votes you have, the higher your page rank (or the better the movie).

In other words the higher the page rank of the person pointing to your page, the better your rankings will be

Page and Brin originally nicknamed their new search engine “BackRub”, because the system checked  backlinks to estimate the importance of a site. Eventually, they changed the name to Google, originating from a misspelling of the word “googol“,the number one followed by one hundred zeros, which was picked to signify that the search engine wants to provide large quantities of information for people. In august of 1998, Sun co-founder Andy Bechtolsheim writes them a check for $100,000 to a company that didn’t even exist yet. It was at this very moment that they realized what they had  and went and incorporated the name Google Inc. Their knowledge was great, but not great enough to impress the money boys or the major internet portals. Oh how they wish they invested in them now! So they began struggling for financial support. Andy was one of the few to see true potential of what these boys had created. During their presentation to him, Andy said he had to duck out for another meeting and offered to write them a check. The check was for $100,000 and that indeed had got things moving for them.

In September the boys moved into the their workspace in Susan Wojcicki’s garage at 232 Santa Margarita, Menlo Park, CA. They then went on to file for incorporation in California on September 4 1998.  Shortly after completing this important task, the boys went an opened a bank account in the name of Google Inc., their newly established company, and deposited the $100,000 dollar check Andy Bechtolsheim had given them. Shortly after they have established there new business they began hiring employees. There first one was Craig Silverstein, a fellow grad student from Stanford as well. They then went on to become the most successful internet company ever. 


Google’s main advertising products and main source of revenue is the “GOOGLE ADWORDS”.

Google AdWords is a service that lets you create and run ads for your business, quickly and simply. Run your ads on Google and our advertising network — no matter what your budget, you’ll only pay when people click your ads.

How Does It Work??

AdWords ads are displayed along with search results when someone searches Google using one of your keywords. Ads appear under ‘Sponsored links’ in the side column of a search page, and may also appear in additional positions above the free search results. That way, you’ll be advertising to an audience that’s already interested in your business. You can also choose to display your ads on Display Network sites in the growing Google Network. 

Google began selling advertisements associated with search keywords.In order to maintain an uncluttered page design and increase speed, advertisements were solely text-based. Keywords were sold based on a combination of price bids and click-throughs, with bidding starting at five cents per click. In Pay-Per-Click advertisements advertisers select the words that should trigger their ads and the maximum amount they will pay per click. When a user searches on Google, ads (also known as creatives by Google) for relevant words are shown as “sponsored links” on the right side of the screen, and sometimes above the main search results. Click-through rates (CTR) for the ads are about 8% for the first ad, 5% for the second one, and 2.5% for the third one. Search results can return from 0 to 12 ads.

Google’s total advertising revenues were USD$28 billion in 2010. AdWords offers  cost-per-thousand (CPM) advertising, and site-targeted advertising for text, banner, and rich-media ads. Google has implemented various innovations in the online advertising market that helped make it one of the biggest brokers in the market. Using technology from the company DoubleClick, Google can determine user interests and target advertisements so they are relevant to their context and the user that is viewing them.


Google slowly started increasing its empire by acquiring  many companies,mainly focusing on small venture capital companies.. In 2004, Google acquire KEYHOLE INC.

Corporate affairs and culture…

Google is known for having an informal corporate culture.  Google was also nominated in 2010 to be the world’s most attractive employer to graduating students in the Universum Communications talent attraction index.

As a motivation technique, Google uses a policy often called Innovation Time Off, where Google engineers are encouraged to spend 20% of their work time on projects that interest them. Some of Google’s newer services, such as Gmail, Google News, Orkut, and AdSense originated from these independent endeavors. In a talk at Stanford University, Marissa Mayer, Google’s Vice President of Search Products and User Experience, showed that half of all new product launches at the time had originated from the Innovation Time Off.

In 2008 Google announced its “project 10100” which accepted ideas for how to help the community and then allowed Google users to vote on their favorites. After two years of silence, during which many wondered what had happened to the program, Google revealed the winners of the project, giving a total of ten million dollars to various ideas ranging from non-profit organizations that promote education to a website that intends to make all legal documents public and online.

The company’s mission statement from the outset was “to organize the world’s information and make it universally accessible and useful…..
