Facebook, owned by Meta makes money by selling space to advertisers who want to reach specific groups of people. They give people a free way to stay connected with friends and family. They stayed on top by buying up competitors like Instagram and WhatsApp to own all the “digital hangouts.” Their secret is that your friends and memories are already there, so leaving feels like leaving a party everyone else is still at. They use Network Leverage to run an Advertising model distributed through social apps.
