A dating website with cams...put the money into some late night TV advertising and some Guerrilla marketing in all the major cities around the world. I also met my wife from Match.com, I am sure others would love to spend a couple of dollars for a membership in order to meet your future partner.
Non-adult, I would promote the sport of one-wall Handball which is currently huge in New York City...and starting to spread.

If someone gave me that money right now...I would put the money into something safe like government securities and let it grow for 10 years...and then leave my day job. 10 years ago I would have day traded that money and thought I would make 10 million...but now I have more sense.
