Introducing the Google AJAX Feed API

The AJAX Search team launched a new API this morning that introduces a subtle, yet powerful new way to integrate syndicated content into your web applications.
The provides functionality that allows webpages to retrieve any public RSS or Atom feed via a simple JavaScript method call. The data can be retrieved in either JSON or XML format, enabling web applications to easily mash up and consume the contents of public feeds. Some of the best content on the web is being syndicated over RSS and Atom channels; this API should help web developers quickly integrate rich external data sources into their web applications, while leveraging Google to do the the heavy lifting of crawling, caching, and content normalization.

History of Google Book Search

In the beginning, there was Google Book Search.

Well, not exactly. But one can certainly argue that the project is as old as Google itself. In 1996, Google co-founders Sergey Brin and Larry Page were graduate computer science students working on a research project supported by the Stanford Digital Library Technologies Project. Their goal was to make digital libraries work, and their big idea was as follows: in a future world in which vast collections of books are digitized, people would use a "web crawler" to index the books' content and analyze the connections between them, determining any given book's relevance and usefulness by tracking the number and quality of citations from other books.

The crawler they wound up building was called BackRub, and it was this modern twist on traditional citation analysis that inspired Google's algorithms – the core search technology that makes Google, well, Google.

Even then, Larry and Sergey envisioned people everywhere being able to search through all of the world's books to find the ones they're looking for. What they couldn't have imagined was that one day they would launch a project to help make it happen. Herewith, a brief tour through some of the major milestones so far:

Happy Birthday, Google!

Five years ago, Google founders Larry Page and Sergey Brin incorporated their tiny company. The reason? So they could cash a $100,000 personal check that had been sitting in Page's desk drawer for a couple of weeks.

As Stanford graduate students, Page and Brin had been working together on a search engine they called "BackRub" since early 1996. By 1998, with the encouragement of Yahoo co-founder David Filo, they decided to start a company, and went looking for investors to back them.

From the official company history:

"As a founder of Sun Microsystems, Andy Bechtolsheim was used to taking the long view. When he saw a demo of Google he knew it had potential. A lot of potential. While he had interest, he didn't have a lot of time. According to Sergey, 'We met him very early one morning on the porch of a Stanford faculty member's home in Palo Alto. We gave him a quick demo. He had to run off somewhere, so he said, instead of us discussing all the details, why don't I just write you a check? It was made out to Google Inc. and was for $100,000.'

"The investment created a small dilemma. There was no way to deposit the check since there was no legal entity known as 'Google Inc.' It sat in Larry's desk drawer for a couple of weeks while he and Sergey scrambled to set up a corporation and locate a few other funders among family, friends and acquaintances. Ultimately, they brought in a total initial investment of almost $1 million."

Google, Inc. was established on On September 7, 1998. Following traditional silicon valley protocol, the founders hired Craig Silverstein, now Director of Technology, as their first employee, and set up shop in a friend's garage. Google at the time was still in alpha, with an index of just 25 million pages, but it was handling 10,000 search queries every day.

The company grew quickly, and on June 7 1999, the company announced that it had secured a round of funding that included $25 million from Sequoia Capital and Kleiner Perkins Caufield & Buyers.

The rest, as they say, is history. The official history page has all these details, and more.

Google: a brief history of the Google search engine

Google is now the most dominant search tool on the web, setting the standards that others try to follow and better, as yet unsuccessfully. It was founded in 1998 - relatively late compared to many of the popular search engines - by Larry Page and Sergey Brin, who were graduate students from Stanford University.

Page and Brin had been working together on a search engine they called "BackRub" since early 1996, but with the encouragement of Yahoo! co-founder David Filo, they decided to start a company in 1998 and went looking for investors to back them. Google, Inc. was established on September 7, 1998. The founders hired Craig Silverstein - who was later to become Director of Technology - as their first employee, and started the business in a friend's garage.

Google was still in an alpha stage, with an index of just 25 million pages, but it was handling 10,000 search queries every day. The search engine and the company grew quickly through word of mouth, initially with regular web users coming across the tool and finding the results to their liking.

Usage spread rapidly through press coverage, awards and recommendations, whilst Google's effectiveness and relevance, its speed and reliability, plus clean visual effects and 'quirky' nature all contributed to a rapid increase in the number of new advocates.

Google took a major step forward in 2000 when it replaced Inktomi as the provider of supplementary search results on Yahoo. Following this it won further successes and provided search data to Yahoo as its primary results, as well as to AOL, Netscape, Freeserve and BBCi in the UK. This gave Google exceptional coverage of web searches and established its reputation as one of the most reliable and accurate search tools, making it the clear market leader.

Despite losing the Yahoo relationship in 2004, Google continued to increase its coverage of the web search market and developed numerous regional versions of its search tool, both in English and other languages, so that its global dominance grew. In the UK, Google now accounts for over 70% of web searches that are made.

Google has also been actively developing a range of search options, including an image search, news search, shopping search (Froogle) and local search options. In addition, following Google's IPO in early 2005 it has set itself on a course for Internet domination and to challenge the position of Microsoft as the leading provider of computer services. There has been a series of announcements of new products, including the email service Gmail, the impressive Google Earth product, Google Talk to compete in the growing VoIP market, Google Base and Google Book Search, which is part of its ambitious project to make the content of thousands of books searchable online

Google has become synonymous with search and has entered the dictionary as a verb - 'to google' something. The expansion and integration of all Google's different services is making it a dominant player in the online market, but to many websites, Google is also the ultimate ranking target that will make a significant difference between the volumes of traffic received from prospective customer ssearching the web.

Early history

Began as a research project in January 1996 , by a student at Larry was soon joined in his research project by a fellow Stanford Ph.D. student and close friend. Larry Page hypothesized that a search engine that analyzed the relationships between websites would produce better results than existing techniques (existing search engines at the time essentially ranked results according to how many times the search term appeared on a pageIt was originally nicknamed, "BackRub", because the system checked to estimate a site's importance A small search engine called was already exploring a similar strategy.

Convinced that the pages with the most links to them from other highly relevant Web pages must be the most relevant pages associated with the search, Page and Brin tested their thesis as part of their studies, and laid the foundation for their search engine. Originally the search engine used the website with the domain google.stanford.edu. The domain google.com was registered on They formally incorporated their company, Google Inc., on at a friend's garage in

The name "Google" originated from a misspelling of " which refers to 10100 (the number represented by a 1 followed by one-hundred zeros). Having found its way increasingly into everyday language, the verb, " was added to the and the in meaning, "to use the Google search engine to obtain information on the Internet.

In the company moved into offices at in home to several other noted technology startups. After quickly outgrowing two other sites, the company leased a complex of buildings in at 1600 Amphitheatre Parkway from (SGI) in The company has remained at this location ever since, and the complex has since become known as the (a play on the word a 1 followed by a googol of zeros). In, Google bought the property from SGI for 319 million.

The Google search engine attracted a loyal following among the growing number of Internet users, who liked its simple design In Google began selling associated with search The ads were text-based to maintain an uncluttered page design and to maximize page loading speed Keywords were sold based on a combination of price bid and clickthroughs, with bidding starting at $.05 per click. This model of selling keyword advertising was pioneered by (later renamed Overture Services, before being acquired by and rebranded as). While many of its rivals failed in the new Internet marketplace, Google quietly rose in stature while generating revenue

A describing part of Google's ranking mechanism (was granted on The patent was officially assigned to Stanford University and lists Lawrence Page as the inventor.

Google's declared a phrase which they went so far as to include in their (aka "red herring" or "S-1") for their noting, "We believe strongly that in the long term, we will be better served — as shareholders and in all other ways — by a company that does good things for the world even if we forgo some short term gains."

The Google site often includes humorous features such as cartoon modifications of the to recognize special occasions and anniversaries. Known as "Google Doodles", most have been drawn by Google's international webmaster, Dennis Hwang. Not only may decorative drawings be attached to the logo, but the font design may also mimic a fictional or humorous language such as Star Trek and The logo is also notorious among web users for Day tie-ins and about the company.

Back before Google? Aye, there's the Rub.

According to Google lore, company founders and were not terribly fond of each other when they first met as Stanford University graduate students in computer science in 1995. Larry was a 24-year-old University of Michigan alumnus on a weekend visit; Sergey, 23, was among a group of students assigned to show him around. They argued about every topic they discussed. Their strong opinions and divergent viewpoints would eventually find common ground in a unique approach to solving one of computing's biggest challenges: retrieving relevant information from a massive set of data.

By January of 1996, Larry and Sergey had begun collaboration on a search engine called BackRub, named for its unique ability to analyze the "back links" pointing to a given website. Larry, who had always enjoyed tinkering with machinery and had gained some notoriety for building a working printer out of Lego™ bricks, took on the task of creating a new kind of server environment that used low-end PCs instead of big expensive machines. Afflicted by the perennial shortage of cash common to graduate students everywhere, the pair took to haunting the department's loading docks in hopes of tracking down newly arrived computers that they could borrow for their network.

A year later, their unique approach to link analysis was earning BackRub a growing reputation among those who had seen it. Buzz about the new search technology began to build as word spread around campus.
