The stigma associated with online dating dropped over the years and people view online dating more positively.

This is a timeline of online dating services that also includes broader events related to technology-assisted dating (not just online dating).

Where there are similar services, only major ones or "the first of its kind" are listed.

Online dating services allow users to become "members" by creating a profile and uploading personal information including (but not limited to) age, gender, sexual orientation, location, and appearance.

Most services also encourage members to add photos or videos to their profile.

Online dating services also differ widely in their revenue streams.

Some sites are completely free and depend on advertising for revenue.

Some have a broad membership base of diverse users looking for many different types of relationships.

Other sites target highly specific demographics based on features like shared interests, location, religion, or relationship type.

Others utilize the freemium revenue model, offering free registration and use, with optional, paid, premium services.

Still others rely solely on paid membership subscriptions.

An online dating service is a company that provides specific mechanisms (generally websites or applications) for online dating through the use of Internet-connected personal computers or mobile devices.
