Think Chrome is just another one of Google’s geeky side-projects? Think again. As Chrome head Sundar Pichai tells CNet, the Web (and now mobile) browser has become very lucrative for the
search giant. Technically speaking, you could say that search is still Google’s moneymaker. But it’s more nuanced that that, as Chrome’s success shows. For one, “Inlike with
searches that come in from Safari or Firefox, Chrome searches are more profitable,” CNet notes. “That's because Google doesn't have to share a portion of search revenue through what's
called TAC, or traffic acquisition costs.”
