Peer 1 Hosting has created an interactive Map of the Internet app that lets users explore the internet’s infrastructure. The app displays a global view, a network view, and a chronological view that shows the evolution of the internet from 1994 to today and even predicts what the internet might look lie in 2020. The Map of the Internet app is available now for iOS and Android in the iTunes App Store and Google Play.
