You can find some more references to cross-national studies here: www.zora.uzh.ch/id/eprint/15...

There a a couple of studies on limited sets of countries and quality indicators, e.g. journals.sagepub.com/doi/10.1177/...; www.tandfonline.com/doi/abs/10.1...; www.tandfonline.com/doi/abs/10.1...; journals.sagepub.com/doi/abs/10.1...;

For those who are interested, some more suggestions I got: Wolfsfeld et al: Building Theory in Political Communication
Mchangama: Free Speech A History from Socrates to Social Media
Matassi&Boczkowski: ToKnow is To Compare
Klinger et al: Platforms, power, Politics
Krupnikov&Ryan: The Other Divide

Alteady on my list! Thanks!
