A true game changer would have to be one that people paid money for, and served ultimately to pay for real journalism. That has also been tried many times, with no success that I'm aware of.
I don't mind paying for news, but most newspapers charge in the range of $20-$40 a month for digital subscriptions which just seems outrageous to me. I can listen to a bottomless well of music for $10/mo on Spotify, watch a huge catalog of shows and movies on Netflix for roughly $10/mo, or subscribe to a handful of newspapers for $200/mo. Is journalism so, so much more expensive to produce than entertainment?
