If Google is the leading search engine for internet users, its linked advertising system, Google Ad Sense, is also taking over most of the business of advertisement space and revenues on the web. Despite its monopoly on the computer OS market, Microsoft does not like to see another player becoming suddenly strong enough to compete with Redmond's Giant in the IT world.
The rumor of Microsoft taking over Yahoo is not new, and could simply be the cheapest and smartest way for Redmond to strengthen its position in the search engine/internet advertising businesses.
If the WSJ reported last Friday that discussions are far to be so advanced, and might simply reveal plans for both companies to team up; it remains clear that Google monopoly and power start pushing other players in the field to find way to collaborate to resist.
