Facebook has announced it will add a dating service to its growing list of new products. The announcement came Tuesday at Facebook’s F8 conference in San Jose, California. The yearly event is for app developers and is a place for the company to show off its latest products and services. Facebook has considered adding a dating app for years. But founder Mark Zuckerberg said he felt now is the right time to begin the service. He said that currently, 1 in 3 marriages in the United States starts with an internet relationship. About 200 million people on Facebook identify themselves as single. Zuckerberg said the new service would be coming soon. He noted that the service will aim to help users build long-term relationships, not just hookups.
