Things that billions of people use

The 'Facebook' logo is reflected in a young woman's sunglasses. Facebook has a billion users. What other things are in the 10-digit use territory?

This final note today -- with a nod to Facebook and its 1 billion users.

Herewith, after a nod to the website BuzzFeed, a partial list of other things that are in 10-digit user territory.

  • Cars and televisions (those are easy).
  • Mandarin Chinese.
  • Catholicism.
  • Cigarettes.
  • And... Microsoft Office (believe it or not).
