Difficult to believe isn't it? Having recently completed the purchase of 'reCAPCTHA', Google has amassed a grand total of 57 companies through acquisition. From it's earliest days in the late 1990's to late summer of 2009, Google has been on the look-out for companies that fit with its aim to become the biggest and best.
The acquisition of reCAPTCHA has received little press attention - which is somewhat surprising when you consider it was an undisclosed purchase price that could be guessed to be well into the super-millions.
Google is often thought of as a monster corporation that is of its own making; but what is less known is how important each of its acquisitions have been in allowing it to gain a head start in the markets it wishes to pursue. Rather than catch up, Google buys the market leader and drives it on under its own brand, bringing the latest technologies inhouse and developing them.
So, what better time than to publish a full list of their purchases with a few notable comments along the way. We've published the purchase price where it was publically released or discovered. Let's start off by showing the logo long before they started their journey of splashing the cash..


...but let's be honest, how much of it is Google and how much of it is a myriad of very clever acquisitions all behind the scenes? Of course you'll find nearly every collosus of the commercial world is built in a very similar way, but it's always interesting to see peoples reactions to how Google has got to where it is today.
Google invented an outstanding search engine, developed a growth business of phenomenal rate - and then it went on the trail of each and every company that could expedite that growth rate to turn it into the giant that it is today.
On a final note, you can easily spot that Google keeps acquiring companies on an almost monthly basis these days. Set yourself up a Google Alert for 'Google acquisition' and you can be assured of receiving e-mails to let you know of their latest intentions as soon as they're announced.
Every company has its failures and Google is no different. Over the years some of the acquisitions it has made have turned sour, as have some of the projects that acquisitions were intended to improve.
Then you have the projects that Google tried internally but then had to go outside to purchase when things didn't work out.
Google Videos was a failure in the face of YouTube, so Google did what all good companies do - it bought the competition.
Google Catalog Search was launched in 2001 as a demonstration of OCR (opticial character recognition) technology and will ultimately be replaced by Google Books. Catalog Search was sent to the archives in January 2009.
Google Notebook was panned a good while back. Promoted as a single portal for browsing, clipping and organising information found online it failed to catch on. Whilst users can still access their portfolio of Notebook clippings, the product is no longer being developed. It was killed off at the same time as Catalog Search.
Dodgeball, a Google acquisition referenced in the main article on this page, failed as a social networking tool and fell to the likes of Twitter.
Jaiku, another acquisition, is to be merged with the Google Apps engine. Development will stop and the original product will be taken care of by a group volunteers in the form of a micro-blogging service.
Google Mashup Editor shut down earlier in 2009.
Google Knol, a supposed competitor to Wikipedia is to close.
Grand Central, a telecoms service has failed.
Google Base, an online database, is next in line for the chop.
See, even the big boys have their failures. It just happens that Google tends to learn from them better than most (and has a lot less failures than successes).
