daria42 writes "An e-mail memo sent from Microsoft chairman Bill Gates to top execs at Microsoft has been leaked, revealing the executive wants his company to hurriedly change its focus and start to tap online advertising and services as new revenue sources. In the e-mail, Gates cites another, earlier memo, sent from MS exec Ray Ozzie, in which Ozzie also warns MS of the importance of focusing on the online medium. 'It's clear that if we fail to do so, our business as we know it is at risk,' Ozzie wrote. 'We must respond quickly and decisively. We should've been leaders with all our web properties in harnessing the potential of Ajax, following our pioneering work in OWA (Outlook Web Access),' he continued. 'We knew search would be important, but through Google's focus they've gained a tremendously strong position.'"
