Speed dating, as two separate words, is often used as a generic term for similar events.
Because the matching itself happens after the event, people do not feel pressured to select or reject each other in person.
On the other hand, feedback and gratification are delayed as participants must wait a day or two for their results to come in.
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.
Other studies found speed-dating data useful as a way to observe individual choices among random participants.
A 2005 study at the University of Pennsylvania of multiple Hurry Date speed dating events found that most people made their choices within the first three seconds of meeting.
Hurrydate was acquired by Spark Networks (Jdate/Christian Mingle). The advantage of online speed dating is that users can go on dates from home as it can be done from any internet enabled computer.
Pre-Dating was acquired by Cupid.com, but eventually became independent again. The disadvantage is people do not actually meet one another.
Specific age range based on gender is a common restriction for events.
