The competitive landscape on search/browsers/os/user-engagement is getting fascinating:<p>Mozilla, who doesn't have an operating system/distribution and therefore isn't the last team to touch an app, has a revenue distribution deal with Google by making them the default search engine of the firefox browser, which has a 25th percentage or so share of the browser market.<p>Said Revenue Sharing deal, is now being undercut by Canonical, the Operating System Vendor, that uses the Firefox Browser, but who has now entered a revenue sharing deal with Yahoo, who uses Bing! as their search back-end. Bing! of course, is owned by the company that Canonical seeks to upend with its 2-3% market share in the Operating System Market. I wonder how Mozilla will feel about their "Branded" firefox browser having it's search engine (and revenue) reprogrammed to point at Yahoo by default? I wonder if they'll force Canonical into switching over to Ice Weasel?<p>Google, has decided to create their own browser, and is now working on their own OS (a linux distro). Google has the ability to do a full stack integration (OS/Browser/Search) - But is weak in everything but Search in terms of market share.<p>Apple, meanwhile, who has a both a Operating System, and Browser, and is now becoming increasingly competitive with Google, may be turning to Bing! for a revenue sharing deal on the browser. Apple has no search engine, has some (but not overpowering) share in the browser/OS market.<p>Finally, there is Microsoft, who, continues to move along with Dominant Operating System and Browser share, and, slowly, increasing their small share (in the teens) of search (though mostly at the cost of Yahoo).
