Other important inventions[edit]

Other significant innovations were made, however they are not included among the top four. Silk and porcelain were the most important for world profit and the growth of the various empires' economy.
They were valuable commercial items exchanged along the Silk Road routes, and when the processes for producing them were understood in Europe and the Islamic world, large businesses grew in both
Television (1920s)
The invention that swept the world and changed leisure habits for countless millions was pioneered by Scottish born electrical engineer John Logie Baird. It had been realised for some time that light could be converted into electrical impulses, making it possible to transmit such impulses over a distance and then reconvert them into light.
Motor Car (late 19th Century)
With television, the car is probably the most widely used and most useful of all leisure inspired inventions. German engineer Karl Benz produced the first petroldriven car in 1885 and the British motor industry started in 1896. Henry Ford was the first to use assembly line production for his Model Т car in 1908. Like them or hate them, cars have given people great freedom of travel.
Electricity
The name came from the Greek word for amber and was coined by Elizabeth I's physician William Gilbert who was among those who noticed that amber had the power to attract light objects after being rubbed. In the 19th century such great names as Michael Faraday, Humphry Davy, Alessandro Volta and Andre Marie Ampere all did vital work on electricity.
Photography (early 19th Century)
Leonardo da Vinci had described the camera obscura photographic principle as early as 1515. But it was not until 1835 that Frenchman Louis Daguerre produced camera photography. The system was gradually refined over the years, to the joy of happy snappers and the despair of those who had to wade through friends' endless holiday pictures.
