Requirements for each event vary with the organizer.
Its origins are credited to Rabbi Yaacov Deyo of Aish Ha Torah, originally as a way to help Jewish singles meet and marry.
Speed Dating, as a single word, is a registered trademark of Aish Ha Torah.
Speed dating, as two separate words, is often used as a generic term for similar events.
At the end of the event participants submit to the organizers a list of who they would like to provide their contact information to.
If there is a match, contact information is forwarded to both parties.
Contact information cannot be traded during the initial meeting, in order to reduce pressure to accept or reject a suitor to his or her face.
There are many speed dating events now in the United Kingdom, Canada, and the United States.
The first speed-dating event took place at Peet’s Café in Beverly Hills in late 1998.
Usually advance registration is required for speed dating events.
Men and women are rotated to meet each other over a series of short "dates" usually lasting from three to eight minutes depending on the organization running the event.
At the end of each interval, the organizer rings a bell, clinks a glass, or blows a whistle to signal the participants to move on to the next date.
