More studliferous research, an interactive table here by 'Sunshineboom' from our favorite ME social media site, https://www.reddit.com/r/retconned . You can see how often each of 3 different Berenstein Bears terms was searched by USA state and you can use the slider bar at the bottom to change the search year, notice that Bernstein was actually not an unusual search at one time in some states like California and those near the Great Lakes. I actually myself remember it being Bernstein back in the 70s. I am including a copy of the same table below as a backup copy in case we lose the offsite copy. Sorry the sizing is not ideal but you can use the scroll bars at the side and bottom to access the whole USA and the time slider bar that is under the USA map.
