1880 : First International Telephone Line Connects Detroit and Windsor

January 20, 2018 all-day

The first international telephone line in the world opened between Detroit and Windsor on Jan. 20, 1880.

A year later, almost to the day, the Michigan State Telephone Co. (later Michigan Bell and now part of AT&T) was founded to deal with long-distance calls, and Detroit’s first public pay phones were installed.
