Google paid $7.2 billion last year to have its apps installed on your phone

Google is one of the most well-known companies in the world, but even so, the search giant still pays a nice chunk of cash each year to maximize profits and visibility as much as possible. Money that Google pays to have Google-served ads on websites, the default search engine on iOS, and Google apps preinstalled on Android phones is referred to as "traffic acquisition costs", and the company pays $19 billion each year for it.
