I think social (cooperative) gaming might be an exception to this. I'm not about to argue that it's _better_ than real-life social interaction, but hanging out and communicating with the same individuals every evening while working on shared goals as your avatars inhabit the screen can combat loneliness for many individuals without (and with!) alternatives[0].
These interactions can even lead to real-life communities and relationships. So again, not a perfect substitute, but certainly not as much a detractor as sitcoms or (I would argue) social media.
