Online dating (or Internet dating) is a system that enables strangers to find and introduce themselves to new personal connections over the Internet, usually with the goal of developing personal, romantic, or sexual relationships.

Still others rely solely on paid membership subscriptions.
Opinions and usage of online dating services also differ widely.
Some sites are completely free and depend on advertising for revenue.
