This is exactly what Baidu (NASDAQ:BIDU) has been doing in recent years. IMHO, the precision of results from Baidu is less competitive in many niche perspectives compared with that from Google, and many keywords draws hoax, sponsored links by liars/copycats/fake suppliers. The reason is obvious. Censorship in various ways blocks Google from entering Chinese market, and the rest of the players are just not strong enough to compete with Baidu. However, Baidu is good in providing the latest rumours and gossips on entertaining subjects/celebrities. Also, Baidu was accused by many to have intentionally removed or weighed down the links to sites, admins of which have refused to bid advertisement or increase their advertisement bidding. I cannot explain such strategy except to hypothesize that Baidu has sustained de facto monopoly.
