Tickle is an online dating service touted by its creators as being more useful, convenient and fast to use than any other Internet dating site. However, Tickle has gained a great deal of notoriety among regular Internet users due to their use of spyware and the resulting popup ads.
History
Tickle was originally founded by James Currier as Emode.com, one of the early innovations of modern Internet social networking. Its matchmaking service was implemented in 2003 and, despite its reputation for being a rather aggressive pop-up campaign, millions worldwide have subscribed to it.
