I find it very difficult to believe that majority of people haven't seen other than mercator projected maps. NatGeo notoriously has used a variety of projections over time. Another fairly notable non-mercator map appears in the UN logo. New York Times seems to use non-mercator maps.<p>Also imho saying that mercator projection is radically inaccurate is misleading, as it is actually very accurate for some things, which is the reason it's afaik used in navigation.
