Do we have any documentation of the "revealed preferences" of the major news publications today? You would imagine that this bias/preference is readily available for internal (national) news outlets just like they are for international news sources. So many employees of these major news outlets have spoken up on the recent forced biased coverage in politics, war-time, conflicts etc. It would be nice to have a live cheatsheet to refer to any active biases being introduced by these major news outlets (and possibly linking their editorial/ownership relationships as well)
