Graphic design has evolved significantly over thousands of years. Some key developments include the earliest known visual symbols dating back 15,000-10,000 BC found in French caves. Paper was invented in 105 AD by a Chinese official, and moveable type was perfected around 1450, allowing images to be added to printed books by 1460. Influential designers such as Chip Kidd, known for book covers including Jurassic Park, Rob Janoff who designed the iconic Apple logo, and Peter Saville, renowned for record sleeves with Factory Records, have helped shape modern graphic design.
