satellite navigation services and is also rumoured to be eyeing the UK property market. The news stories of Google's latest product launches saw the share prices of leading companies in these sectors tumble; SatNav firm TomTom lost a third of its market value overnight, while property website RightMove suffered an initial 13% slide in value. The message from the financial markets seems to be clear - if Google move on to your patch using their "free" services model, you're as good as dead. OK, Google is a massively successful company - in the space of a decade they've grown from nothing to become arguably the most powerful online business in the world - but should their competitors really just roll over and give up? Of course not. Google do enjoy great success, but they are not the great innovators or invincible combatants they are commonly believed to be. To illustrate the point, take a look at how some of their ventures outside natural web search have fared:
Now a key part of its service offering, providing people with other people's news stories was a great idea, although the content creators do seem to be cottoning on to the fact that they're getting the thin end of the wedge.
Perhaps not a revolution, but it certainly did a lot of evolve an email market dominated by the stagnating Hotmail and Yahoo! Mail services. One of the most popular email services around.
Advertising and pay-per-click is how Google managed to make money out of its search dominance. Not originally developed by Google; they acquired Applied Semantics ($102 million) and later DoubleClick ($3.1 billion).
Google Maps / Earth are popular free services. Free for the end user that is, not Google, who bought the technology in a number of acquisitions, notably Keyhole Inc.
If knowledge is power, then with Google Analytics residing on 40% of the 10,000 most popular websites in the world, Google's power is unrivalled. Analytics was the result of another acquisition; Urchin Software. Development of the service has been aided by the subsequent purchase of Measure Map and Trendalyzer.
Google's revolutionary browser hasn't made a huge impact on Internet Explorer or Firefox, but it's doing OK. Much touted "sandbox" tab functionality originates from the acquisition of security firm GreenBorder.
The answer to big rivals' Micrsoft's Office suite; very little impact, borderline failure. Component parts (word processor, spreadsheet, presentation software) bought in purchases of Upstartle. 2Web Technologies and Tonic Systems.
Android is an open source mobile operating system, primarily competing against Apple's iPhone platform; not yet widespread but growing steadily. Acquired with Google's purchase of Android Inc.
Knol is Google's own version of Wikipedia. Little exaggeration to say it has disappeared without a trace. Developed as an internal Google project.
Photo album software and web album; lost the battle to Yahoo's Flickr. Acquired in 2004, Picasa was one of Google's earlier purchases.
Created to compete with YouTube. When it didn't really catch on, Google decided it would be easier to just buy YouTube for $1.65 billion.
Lively was Google's answer to the much-hyped "virtual world" application Second Life. Launched in July 2008, closed January 2009 due to lack of interest.
Orkut was a social networking service designed to compete against MySpace and, latterly, Facebook. Only ever really took off in Brazil, leading to hosting being moved from California to Brazil in 2008.
