Deja News (Google Groups) - This web-based Usenet archive started life in 1995. Between 1999 and 2000, Deja overexpanded into a comparison shopping portal. Losing money, Deja sold the shopping component to eBay in late 2000, and it became part of Half.com. In February 2001, the big G entered the game and snatched up the Usenet archives, reintroducing them as Google Groups and extending them back to 1981 with the help of private collections. Today, Google Groups features Deja's Usenet, mailing lists, and Yahoo! Groups-esque features with a Gmail-like interface.
Outride - Outride, Inc. was an information retrieval spin-off from Xerox Palo Alto Research Center (PARC). Google acquired certain technology assets in September 2001 and quickly integrated them into its search engine. Outride.net currently forwards to Google.
Applied Semantics - Google bought up this contextual advertising company in April 2003 and used it for its AdSense/AdWords services, allowing it to compete with Yahoo!'s Overture.
Kaltix - This 3-person personalized search startup company was quickly picked up by Google in September 2003. Kaltix formed the foundation of Google Personalized Search. Kaltix.com currently forwards to Google.
Blogger - Blogger was the flagship product of Pyra Labs. For a long time, Blogger was free of fees and ads, but it wasn't making money. After the original capital for Pyra dried up, a number of employees resigned, including the co-founder. In an effort to become profitable, Pyra introduced the ad-powered Blogspot hosting and the pay Blogger Pro service. It wasn't quite enough, and Pyra needed more resources, so Google stepped in during 2003. Blogger was redesigned by professional web designers in May 2004, and is now one of the most-used blogging tools.
Picasa - Picasa, a $30 photo organizer program, was first released in October 2001. In May 2004, Picasa announced integration with the Google-owned Blogger, and in July 2004, Google bought the company. Soon, Picasa was free, and it featured Google trademarks like an "I'm Feeling Lucky" button. The software routinely wins awards from leading PC publications.
Keyhole - Keyhole is a digital mapping company founded in 2001. Presumably to cut out the middleman for the not-yet-released Google Maps, Google bought them in October 2004. Since then, there has been an immediate price reduction for the Keyhole software (from $69.95 to $29.95), and integrated satellite photos in Google Maps.
Zipdash - Google acquired this traffic/mapping company in 2004 and put it to work in Google Maps. Although the acquisition was not publicized, Zipdash is mentioned in Google's 2004 annual report.
Where2 - This Australian mapping company was also mentioned in the 2004 annual report, but not much is known about it. It also had something to do with Google Maps.
Urchin - In March 2005, Google acquired Urchin, a web analytics and statistics company. Though we haven't yet seen what they're up to with it, it will probably be used with AdWords/AdSense, with statistics about clickthroughs and such.
Dodgeball - Google acquired this two-person cell phone social networking company in May 2005. The company was looking for investors, and Google apparently fit the bill. So far, nothing has happened with this company, but it will probably have something to do with Google Mobile.
Technorati - If Google is the average person's homepage, Technorati is the homepage of the underground, tech-savvy web user. Technorati is a blog portal whose average visitor enjoys podcasts, Wikipedia, and the Daily Show with Jon Stewart. Providing more cutting edge results than a normal search engine, Technorati would integrate well with Google News and/or Blogger, and could perhaps feature blogs on the Google Personalized Homepage. Technorati is somewhat similar to Bloglines, which was purchased by Ask Jeeves recently. MyOpinion:Technorati is mindboggling becoz it scans all the blogs around the world very quickly and the searc results are apt. What I was missing there was a more refined, context sensitive(like Yahoo Mindset) and clustered results. A single search what the search engine gives is never going to help, so Google as act big here. My name for this woul be 'Google Technorati'.
Koders - Koders is a search engine for open source code that works remarkably well. With the recent push for plugins for Google Desktop search, Koders would be an interesting addition to Google's software initiatives. It would make sense to combine with Google Code and Google Linux Search in some way. MyOpinion: Koders really has been amazing and I have fallen in love with it. As a techie I expect more code snippets other than tutorials which are over populated over the internet. If not google Koders can have deals with sourceforge.net, freshmeet.net and many other opensource sites to bring a new way. If Koders can include something like 'recommended tutorials','search for tutorials','search theories/algorithms', etc would make it more techie and make every novice's one stop search point. Hope Google can do a lot more value. My name for it would be "Google Grep"
GuruNet (Answers.com) - Recently, Google stopped linking to definitions on Dictionary.com, and started linking to Answers.com instead. Answers features a wealth of information about different topics, and uses Wikipedia for much of it. Since Wikipedia's non-profit status rules it out as a potential Google acquisition, Answers.com would be the next best thing. It also would help improve Google Q&A quite a bit. Interestingly, GuruNet is a publicly traded company (AMEX: GRU) with a market cap of about $100 million. MyOpinion: Anwears.com has always been my choice for searching silly as well as important things which I dont understand. It UI is plesant and it does not overload me with informatio by presenting only what is relavant to know about something at a glance. One thing is some recommended links and I belive a person searching for something comes for that only onces. For the second time also he is presented with the same basic material which is annoying. A login using cookie and maintain the user pattern and inform more as he comes again and again. Answears.com has all the capacity to become an internet 'Oracle'. With google Answears.com can speak out more. My name for it would be 'Google Oracle'.
Clusty - Clusty is just not another search engine which we think. The main advantage of searching using clusty is that the results are clustered into major subclasses using 'Cluster By' option. So the search experience here is for both the normal users and the context-sensitive users. This search is really amazing and I am getting addicted. MyOpinio: I think clustering is missing in anyof the search engines which make this unique. When I search I need not check each result with what I want so clusty provides me another level of refinement. Google would mean more if it acquires Clusty. My name for this would be 'Google Clusty' giving honor to the orginal Clusty.
Skype - Skype has changed the rules of communication with the help of internet. Skype is generally used by people for calling other phones or systems. Skype is the most widely used VOIP tool across the internet. MyOpinion: I would love skype to be a part of google family. Skype can really add lot more value to Google with its exsisting customer base and functioinality. Acquiring Skype would be tremendous and I think they can accept any amount of deal since they have IPO.
del.icio.us - This social bookmarking and tagging application could be used to improve Google search results, and perhaps integrate with Orkut in some way. Were Google to buy Buzznet as suggested above, this would work well with it. MyOpinion: Good but I needs to concentrate on its UI.
StumbleUpon - This unique browser plugin and service would probably improve Google results and add a new level to the venerable search engine. It would probably combine with the Google Toolbar in some fashion, since the two have some similar functions. MyOpinion: StumbleUpon has a free toolbar which brings internet alive. The toolbar is used to stumble and give reviews about each site the community browse. I think surely Google can integrate it with it Google Toolbar which must be provided for every available browser. Still today Google is ranking sites on basis of content but with Stumble google can add a more dimensions to its search. When I search for a keyword it gives its original result but it can have another link called 'what users liked?' , 'user experience feel' and many such alive data. Hope this would take long time but it would really make google more social.
Propel - Similar to Google Web Accelerator, Propel claims to speed up your browsing experience. The company is run by optical mouse inventor Steven T. Kirsch, who is no stranger to buyouts: his Frame Technology Corp. was purchased by Adobe, and his Infoseek was bought by Disney. This could help Google out with Web Accelerator, which it has been having trouble with. MyOpinion: I checked their site as Propel is new to me. The statistics sound compitation to Google Web Accelerator but still not popular. Its mainly targeting the home PC users. Must Google can join hands with Propel to bring in an ISP version or Web Accelerator Pro for large companies. I am really a novice here but just wanted to present my idea.
Monster - Monster is the most popular job search site. Some bloggers have tossed this idea around, touting various forms of integration with other Google services. They also mention that Yahoo! owns HotJobs. However, one wonders whether Google is interested in this market at all. MyOpinion: Monster is too big and well known to get acquired. The world of man power and opportunities are growing drastically. The estop is to provide an onestop site for all the career inforamation. My name for this would be 'Google Path'.
World66 - World66 could be Google's answer to Yahoo! Travel, with some work. Its Wiki style, however, might be too wild for Google's liking. MyOpinion: Google presently has not provided any services focusing on the travel industry. Travel industry is the most dynamic industry growing leaps and bounds. I think World66 can be powered with Google Maps to give the ultimate solution. But when compared to Yahoo Travel!, World66 must atleast undergo another 10 major updates. But empowered with Google, World66 can really turn world class. My name for this would be 'Google Travel'.
Stayhealthy/Fitness Expert - This online health company doesn't offer content a la WebMD, instead providing health and fitness hardware, self-test kits, and a kiosk joint-ventured with IBM. The hardware interface is web-based. As with TiVo, Google's limited hardware experience may be a problem, and one wonders whether Google is interested in the health and fitness space. MyOpinion: Google still now has worked for the ease of user experience on Internet. Now for google to continue it has to even take care of that internet user. I find every reason for the evolution of 'Google Doctor'/'Google Health'.
Audioscrobbler/Last.fm - So far, Google hasn't made any inroads into the music industry. However, these sites together form an interesting, Google-ish service that uses algorithms reminiscent of PageRank to calculate the top artists and similar info. MyOpinion: Its clear in the above sentences but 'Google Music' with searchable interface would be right find.I know there are lots other stuff Google would be eying on but just trying to find out whether 'Google is trying to think like me.'
