eli5: How can Google maps know many small and recent businesses’ locations so accurately?

Question

I’ve realised that most businesses (even small kiosks) are seen on Google maps. Where and how do they get that information?

places.google.com lets you add your company. This is also where you add your phone number and opening hours. It is really a missed opportunity if companies do not fill this in, it doesn’t take long and it’s free.
