The Undertaker's Revenge
The automatic telephone exchange was invented in 1891 by Almon Strowger — an undertaker who believed telephone operators were routing his calls to a competing funeral home.
Phones vs. Toilets
6.8 billion people have access to a mobile phone, but only 4.2 billion have access to a working toilet. Mobile phones have outpaced basic sanitation worldwide.
The 1.1 kg Phone Call
The first mobile phone call in 1973 was made on a Motorola DynaTAC that weighed 1.1 kg (2.4 lbs). Today's smartphones weigh about 170 grams.
$75 for 3 Minutes
The first transatlantic phone call in 1927 from New York to London cost $75 for just 3 minutes. Adjusted for inflation, that's over $1,300 today.
Samuel Morse Invents the Telegraph
Samuel Morse developed the electric telegraph and Morse code, enabling instant long-distance communication for the first time in human history. The famous first message: "What hath God wrought."
