Microsoft is not plotting against search giant Google with Internet auction company eBay, though the two companies communicate often and could work together in the future, Reuters reports.The news comes from a Friday report in German newspaper Die Welt, in which Microsoft\u2019s Chief Executive Officer Steve Ballmer spoke of the report earlier this week that implied Microsoft might be teaming up with eBay and Yahoo, the world\u2019s second-largest search firm, to overthrow Google, according to Reuters.\u00a0 For more, read Report: EBay Looks to Microsoft, Yahoo to Fight Google.\u201cOf course we talk with eBay all the time. But we don\u2019t get together in a secret circle and hatch plans about what we could do together against Google,\u201d Ballmer told Die Welt, according to Reuters.In early April, Google saw a revenue jump of just under 80 percent, and it snatched up an even bigger slice of the search pie, Reuters reports. This type of speedy growth, as well as Google\u2019s plan to offer an online classified service, has led eBay to begin considering collaboration efforts with companies like Microsoft, according to Reuters.Though Ballmer acknowledged being close friends with eBay Chief Executive Meg Whitman, he shot down the idea that the two firms would join forces and mount an offensive against Google, Reuters reports.\u201cA tie-up with the sole aim of shutting out a competitor makes no sense,\u201d Ballmer said, according to Reuters. \u201cThe partnership must produce something that is useful for users and advertisers.\u201dThis article is posted on our Microsoft Informer page.
