Los Angeles magazine has a feature by by Dave Gardetta about father-son team who runs Doc Johnson, a North Hollywood business that manufactures more vibrators, plugs, and sexual prosthetics than any other company in the U.S.
Doc Johnson [is] the country’s biggest sex toy manufacturer, a six-acre industrial park in North Hollywood that employs 500 people and fabricates about 2,500 items — including the Pocket Rocket vibrator, the John Holmes penis pump, the Cuddles clitoral bumper, Li’L Gum Drops butt plugs (sold in pink or blue), Dr. Honn’s Erection Ring ("Feel the Power"), and Kimmi, an anime love doll that arrives with her own “removable vagina.”
