Online dating or Internet dating is an example of a dating system and allows individuals, couples and groups to meet online and possibly develop a romantic or sexual relationship. Net dating services provide un-moderated matchmaking through the use of personal computers, the Internet, or even cell phones.
 
Such services generally allow people to provide personal information, then search for other individuals using criteria 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, and message boards. Sites sometimes allow people to register for free but may offer services which require a monthly fee.

Many sites are broad-based, with members 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.
