I remember Skype being used by everyone for everything up until 2016-2017. Even when meeting people online it wasn't uncommon to exchange Skype handles so that we could voice chat. Then it really just... disappeared.
Combination FaceTime, discord, zoom, Google meets even, probably more, all taking off. Used to not have many choices if you wanted to video/voice call people. Now it seems every social app has it baked in.
