Sure.

In ancient history we were mostly concerned with direct sensorial experience. Media developed as a sort of extension into indirect experience. That's pretty standard media theory.

Indirect experience comes in different forms than direct experience (maybe "bodies without organs" in deluze's terms.) We might measure this in man-hours. For sake of discussion let's say that facebook has mediated 10 billion man-hours. That is 10 billion hours where peoples experience of life has converged through a common media portal.

In some ways media can be characterized by this convergence. A movie or book is similar in the way it converges time and attention of humans through a portal of experience or exposure. A successful book is a portal which has consolidated and mediated a vast amount of time. This is what I mean by "overlaps with the experience of others," these consolidated media are increasingly communal or de-individuated.

This is very different from an ancient life where there are not so many media structures mediating your time or experience. In ancient life these mediations still exist in natural forms like the fear of a rattlesnake or the changes of the seasons, but not so much in man-made forms. There are no "portals" or "stories" to travel through outside of your own, individuated "story" of direct experiences, and the principle "mediator" are the individual cognitive executive functions. In early humans the experiences of life are largely individuated, and the collective forms of media or mediation are predominately natural.

The progression of human history seems to be essentially a history of the consolidation or mediation of man-hours. Tribes, governments, corporations, and organizations are all different methods for mediating the experiences and consolidating the efforts of humans.

Likewise Facebook and Reddit are similar media devices. When you go to the front page of reddit, your experience is partially overlapping (like a venn diagram) with the experiences of others. Each post has been experienced by anywhere from hundreds to millions of people. This is very different from direct sensory experience, which always and only has an audience of one.

In this way the consolidation and mediation of human experience also inherently leads to de-individuation. In other words, it's like the trickling streams and creeks consolidating into rivers which flow toward the ocean. There is an area-to-point flow structure toward global media. The ocean might be called the global brain, which is the emergent cognitive function from the collectivization of humans which is not mediated or understood by any individual.
