A cartel capped light bulb lifespans at 1,000 hours

In 1924, the world's leading light bulb makers formed the Phoebus cartel in Geneva. They carved up markets and set a rule: a bulb must not last more than 1,000 hours, even though some had lasted far longer. Manufacturers whose lamps lasted too long were fined. Active until World War II, the cartel remains the best-documented example of planned obsolescence.

The fax machine was invented before the telephone

In 1843, inventor Alexander Bain patented a way to send images over telegraph wires using synchronized pendulums. By the 1860s, a commercial fax service was already linking cities. The telephone wasn't patented until 1876, more than three decades after that first fax patent. The fax is really a child of the telegraph age.

The first pacemaker patient outlived its inventors

On 8 October 1958, in Stockholm, 43-year-old Arne Larsson received the very first implanted pacemaker. The device, designed by engineer Rune Elmqvist and implanted by surgeon Åke Senning, worked for only a few hours and had to be replaced. Larsson went on to receive more than twenty pacemakers in his lifetime. He died in 2001 aged 86, outliving both the engineer and the surgeon.
