Chabad won in media a long long time ago. They were always quick to embrace new technologies as ways of reaching people, while the Chassidish, Yeshivish, and Modernisch oiloms were much more hesitant. Therefore references to frum Yiddishkeit on TV, movies, and the internet are almost always from a Chabad perspective. A lot of people who know mostly of minhagim through the Internet think that things like the day the Ba’al HaTanya was released is widely celebrated, or that there’s only one person referred to as “the Rebbe”.
