The Push for a “PBS for the Internet”
A few posts here bring up the BBC and while it is an interesting case because they are so specifically funded by the public through a "TV License" [1], I think maybe a better comparison for this "Public Internet" should be to CSPAN.Using the CSPAN model, a public good commons of internet services would be carved out through an offset program in  Wireless Spectrum auctions and other Telecom Service Provider Licenses and renewals [2].  Maybe if they ever get around to the Big Tech Tax that could help too.[1]   You must have a TV Licence if you: watch or record programmes on a TV, computer or other device as they're broadcast. download or watch BBC programmes on iPlayer – live, catch up or on demand.

   £159 for a colour TV Licence and £53.50 for a black and white TV Licence
