Online dating or Internet dating is a dating system which allows individuals, couples and groups to make contact and communicate with each other over the Internet, 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.
Online dating services generally require a prospective member to provide personal information, before they can search the service provider's database for other individuals using criteria they set, such as age range, gender and location. Most sites allow members to upload photos of themselves and browse the photos of others. Sites may offer additional services, such as webcasts, online chat, telephone chat (VOIP), and message boards. Some sites provide free registration, but may offer services which require a monthly fee. Other sites depend on advertising for their revenue.
Many sites are broad-based, with members coming from a variety of backgrounds looking for different types of relationships. Other sites are more specific, based on the type of members, interests, location, or relationship desired.
