Number of Slinkys sold since the toys invention in 1945:

300 million
Slinkys were invented by a naval engineer named Richard James after he saw a spring fall off a table and “walk.” His wife Betty was so unsure of the idea that she asked a friend to go and buy one when the first 400 were offered for sale at Gimbels. There was no need to worry -- they sold out in 90 minutes. Mrs. James named the toy, picking the word out of a dictionary because she felt the word "slinky" best described the toy's sound and movement.
