Google may be the most-popular search engine in the world, but its continued dominance doesn’t come cheap. Plenty of people never bother to change their default search engine, which means that securing exclusivity deals is essential to the success of a search engine, to the point where it’s worth paying hundreds of millions of dollars in some cases. According to some information that was released thanks to Oracle’s ongoing legal battle with Google, the latter company shared as much as 34% of the revenue that Google Search earned through iOS with Apple back in 2014, which amounts to about a billion dollars, in order to ensure its search bar remained on iOS.
