All I can say is, Wow.

Slate.com has a fascinating slide show about the history of the vibrator. Check out these choice quotes:

"By 1917, there were more vibrators than toasters in American homes."

...

"Also popular were vibrators that doubled as nail-buffer kits, hair brushes, backscratchers, and some that were designed as attachments for vacuum cleaners."

...

"In 1999, Rachel Maines published The Technology of Orgasm, a provocative history of the vibrator that she spent 20 years researching. Maines started out studying needlework but was intrigued to discover that the backs of old sewing magazines were filled with vibrator advertisements. In addition to treating hysteria, these early vibrators were multipurpose: They ostensibly relaxed furrowed foreheads, cured sore throats, and restored plumpness to bony arms."
