Google "gives away" a great search engine, among other features. That's great. But how do they pay for it? What is Google's business model?
In a nutshell: advertising revenue. Both on Google's site and on other sites.
Google is a major player in the online advertising industry. Every time you search Google, you'll see ads displayed along with your results. Those ads are never "mixed in" with the results - there is no "pay to play" on Google... which is one of the reasons Google became the most popular search engine in the first place. But the sponsored text-link ads above and to the right of the results generate a great deal of money for Google. These ads are known as "Google Adwords." Those who wish to advertise via Google can learn more on Google's Adwords page.
In addition, you may have noticed columns or boxes containing similar text-link ads on other websites - such as this one - which say "Ads by Google" at the top. Google already had a powerful system for selling and displaying ads in association with their own search engine. From there, it wasn't much of a jump to start displaying ads on other websites. Webmasters of popular sites with interesting content can sign up on Google's Adsense page and begin displaying Google ads to their users. Google pays the webmaster a portion of the advertising revenue and keeps the rest. This service is called "Google Adsense."

WWW FAQs: How many websites are there?
2007-02-15: How many websites exist? How big is the World Wide Web? Since no one is in charge of the World Wide Web, the question is difficult to answer precisely. After all, there is no one central "server" that runs all the websites in the world. The DNS registrars have lists of the domain names that exist, but not every domain contains a website, many domains contain more than one, and the registrars are not under any obligation to tell the rest of us exactly how many domains their databases contain.
So what can be done to measure the size of the World Wide Web? Has anyone tried? Yes! The Netcraft Web Server Survey is a widely respected survey that attempts to contact each and every website that is accessible on the Internet.
Netcraft's primary goal is to determine web server market share: what percentage of websites run Microsoft's Internet Information Server, versus the Apache web server? But fortunately for us, they also count the websites visited by their automatic web-exploring "spider" software. And in February 2007, the Netcraft Web Server Survey found 108,810,358 distinct websites.
Of course, Netcraft's survey isn't perfect - there may be websites in the world that were not discovered by Netcraft's software. So, as of this writing, "there are more than 108 million websites" is the most accurate statement that can be made.
"But how many web pages are there?"
Large websites can have many thousands of pages. Dynamically generated sites can have a seemingly infinite number - and we must somehow agree not to count all of these. Yet most sites just have a few pages introducing a business or a person, or simply a placeholder home page.
Who could possibly tell us how many web pages there are? There are two obvious candidates: Google and Yahoo, the major search engine companies. Visiting, analyzing and indexing the billions of web pages in the world is their business. Unfortunately, neither company currently publicizes the exact size of its index and they have not done so since August 2005.
Is there anything we can do to arrive at a realistic estimate at the number of pages on the web? Yes: we can look at those August 2005 web page numbers, divide them by Netcraft's count of web sites in August 2005, and arrive at an estimated number of web pages per site. Assuming that the number of web pages per site has not changed drastically in a year and a half, we can then multiply Netcraft's February 2007 count of websites to arrive at a reasonable projection of the number of web pages in in the world as of February 2007.
So let's run the numbers!
Web pages in the world, August 2005: 19.2 billion pages were indexed by Yahoo as of August 2005.
Websites in the world, August 2005: 70,392,567 websites were indexed by Netcraft as of August 2005.
Web pages per website: 273 (rounding to the nearest whole number).
Web pages in the world, February 2007: multiplying our estimate of the number of web pages per website by Netcraft's February 2007 count of websites, we arrive at 29.7 billion pages on the World Wide Web as of February 2007.

Microsoft Wants Smaller Software Footprints Starting With Windows 7
Microsoft will use a bare-bones version of the Windows kernel, called MinWin, as the starting point for the development of future products, including Windows 7 and Windows Server.
Microsoft apparently is putting its Windows operating system on a diet.
Acknowledging criticisms that the Windows operating system is "bloated," a senior company official said the software maker has adopted a new, modular approach to OS development that will yield more streamlined products beginning with Windows 7 -- a successor to Windows Vista that's expected to be available some time in 2010.
"We're starting on this path," said Microsoft distinguished engineer Eric Traut, during a presentation at a college campus.
"A lot of people think of Windows as this large, bloated operating system. That's maybe a fair characterization," said Traut, who was speaking last week at the University of Illinois. A video of his presentation appeared Friday on the blog IstartedSomething.com.
With an eye toward offering slimmer products, Microsoft will use a bare-bones version of the Windows kernel, called MinWin, as the starting point for the development of future products, including Windows 7 and Windows Server.
Microsoft programmers will use MinWin as a base for development and then layer on only what's needed for particular Windows versions. "There's a really nice little core inside Windows," said Traut.
In adopting a more modular approach to Windows development, Microsoft may be bowing to criticism that current, one-size-fits-all versions of the OS are overstuffed for many user requirements. To prove his point, Traut demonstrated a version of MinWin built on 25 Mbytes of data, compared to Windows Vista's 4-Gbyte footprint.
"We've taken a shot at stripping out all the layers above and making sure we have a clean architectural layer," said Traut.
Microsoft has no plans to "productize" MinWin, but will use it as the basis for future OS development. "We're definitely going to be using this in a lot of the products we build," said Traut.
Microsoft may be hoping that the Windows-on-Weight Watchers approach will help it fend off competition from Linux and Web-based software -- non-Microsoft computing alternatives that impose less demanding hardware requirements on end users.
Despite the fact that Windows Vista launched earlier this year amid considerable hype, many consumers and businesses have shied away from the OS, citing cost and compatibility concerns, in addition to Vista's steep resource requirements.

SanDisk Launches PC-To-TV Player And Online Video Service
SanDisk Launches PC-To-TV Player And Online Video Service
SanDisk on Monday launched a PC-to-TV video player that lets users download content from a USB port, and then carry the files over to a living room television for playback through standard audio/video sockets. In addition, SanDisk also unveiled a video download site called Fanfare which would compete with Apple's iTunes music and video store.
SanDisk is calling the device Sansa TakeTV, and claims that it's a simpler alternative to setting up a wireless network, running wires across a living room, or burning video on a DVD. "Sansa TakeTV is the most easy-to-use, straightforward solution for watching downloaded personal video content and other shows in the comfort of the living room," Daniel Schreiber, senior VP and general manager for SanDisk's audio/video business unit, said in a statement.
Apple and Microsoft have added features to their operating systems to make the Mac and PC, respectively, act like a digital video recorder for content downloaded off the Web. Most consumers, however, prefer to avoid the complexity of setting up a wireless or wired network in order to connect their computers to a TV, experts say. SanDisk is trying to get around these hurdles by offering a device that's similar to a USB flash drive.
To use the device, consumers would plug it into a USB port on a PC or Mac, and drag video files on the computer to the device. Consumers would then slip the gadget into a cradle plugged into standard A/V sockets on the TV and see an on-screen guide to select content using TakeTV's remote control.
"It's actually a good idea because companies have been challenged in making that connection (between the PC and TV)," said Steve Wilson, analyst for ABI Research. "And they're leveraging a model that people are very familiar with."
SanDisk also was smart in not focusing on the delivery of high-definition content, which would have made the device too expensive for average consumers, Wilson said. Launching Fanfare was also a good idea, because it gives customers a place to go immediately after buying the device, rather than having to look for their own content.
The product supports video formats DivX, XVID, and MPEG-4, as well as the Vista, XP, Mac, and Linux operating systems. The TakeTV player costs $100 for 4-Gbytes of storage, which holds about five hours of video. An 8-Gbyte version that holds up to 10 hours of video costs $150.
Fanfare, which was launched in beta on Monday, offers TV shows for download. The service requires the user to first download software to access the online store and manage downloaded content. The site offers free and paid video. The latter typically costs $1.99 an episode.
While Apple's iTunes is the most popular music and video service on the Web, the company has had its problems with content providers. In August, Apple said it would not offer NBC Universal's lineup of new shows for the upcoming TV season because of a rift over pricing. NBC wanted to double the wholesale price Apple pays for each TV episode, a move that would have forced it charge customers $4.99 per episode instead of the current $1.99.

Cash reward for Facebook programs
Software developers will be offered up to $250,000 (£125,000) to develop applications for popular social network Facebook, the site's founder has said.
Mark Zuckerberg announced incentives to firms and individuals who create "innovative and disruptive programs".
There are already around 4,000 of the small programs available on the website.
They include music and digital gifts, games of scrabble and fortune cookies.
The fbFund grants, announced at the TechCrunch40 conference in San Francisco, will come out of a $10m pot gathered by Facebook's primary backers Accel Capital and The Founders Fund.
"With just a little bit of capital, a company can grow to hundreds of thousands of users," Mr Zuckerberg said.
Growth spurt
Applications - small programs that can be embedded in a user's profile page - have exploded on Facebook in the last four months since the social network allowed outside developers to write programs for the site.
Popular applications include the scrabble game Scrabulous, and the music-sharing service iLike.com. These applications have added to the popularity of Facebook. The firm says it now has 41 million active users, whilst some estimates suggest that the site now accounts for 1% of all web traffic.
Mr Zuckerberg said he hopes the new scheme, known as the fbFund, will help continue that growth. "We're doing this at Facebook to support the ecosystem and help it grow," he said.
The awards will be determined by a panel that includes Mr Zuckerberg, PayPal co-founder Peter Thiel and Accel's Jim Breyer.
"Any application developer can submit their application and a little business proposal to us," said Mr Zuckerberg. "If we think the project is good we will give a grant for somewhere between $25,000 to $250,000." The only restriction is that companies must not have taken any venture capital money previously. Any firm that wins money will not have to give up equity to the fund.
Instead, it asks that they are given first chance to invest in any successful company that sprouts as a result of the grant scheme.
"This is a grant to help these companies get off the ground," said Mr Zuckerberg.
