Radio, TV, and magazines all have the same thing in common: from the user perspective, they’re read-only. As broadcast media, their scaling models work differently than social media, which includes the storage and/or transmission of user-created data. If Google, Facebook, et al had no costs whatsoever involved in scaling their businesses, then they could be replaced by non-profits providing the services pro-bono.
