Online dating or Internet dating is a personal introductory system where individuals can find and contact each other over the Internet to arrange a date, usually with the objective of developing a personal, romantic, or sexual relationship. Online dating services usually provide unmoderated matchmaking over the Internet, through the use of personal computers or cell phones. Users of an online dating service would usually provide personal information, to enable them to search the service provider's database for other individuals. Members use criteria other members set, such as age range, gender and location.
