From Morse's first telegraph in 1837 to 5G networks and satellite internet — explore the milestones that connected our world.
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.
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 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.
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 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."

Country code +888 is reserved for Universal International Freephone Numbers (UIFN) — international shared cost services.
South Sudan received country code +211 in 2011 after gaining independence — the most recent new country code assignment.
