Nokia began in 1865, when engineer Fredrik Idestam set up a paper mill in south-western Finland, then opened a second mill near the town of Nokia, which gave the company its name. In 1967 it merged with a rubber maker and a cable maker, and the group went on to produce boots, tyres and cables. After refocusing on telecoms in the 1990s, it became the world's biggest seller of mobile phones in 1998.
That's the estimate from a WHO-led study published in The Lancet in 2024, covering the half-century since the Expanded Programme on Immunization was launched in 1974. It works out to about six lives saved every minute, mostly infants. The measles vaccine alone accounts for around 60% of those lives.
According to the World Gold Council, about 216,000 tonnes of gold have been mined in all of human history. Because gold is so dense (19.3 tonnes per cubic metre), it would fit in a cube about 22 metres on each side, roughly the height of a seven-storey building. Strikingly, about two-thirds of it has been mined since 1950.
