- During the 1880s a Victorian physician, Dr. J. Mortimer Granville, invented an electrical device to massage away muscle aches, the vibrator. 

- Granville credits the creation of the device towards his attempt to help ladies with their "female hysteria."

- By the 1920s, these "vibrators" were appearing in early pornography so advertisers felt uncomfortable trying to sell them in newspapers next to other household goods.
