As a person who grew up without a television at home (I was homeschooled in Canada), this is strikingly obvious. Even the differences in mentality and worldview between those who grew up watching American TV shows and those who didn't is immediately obvious to me within 5 minutes of having a casual conversation. One of the reasons I left Canada and moved to Eastern Europe is for the refreshing change in monoculture: I can have normal conversations with people whose minds have not developed in a Hollywood Matrix, whose entire cultural context is not based on popular TV references (or the tropes presented in them). Lots of people in post-Soviet countries don't watch American television, and it is very easy to tell when they do. I now strongly prefer European TV productions (especially older British and French stuff), because the American superpower-worship and military propaganda, and now wokeism, is positively cringeworthy.
