It's very well not statistically accurate, but I multiplied the year by how many shows were in that decade (1940 x 3=5280). Then, after taking the sums from each decaded, I added them all up and divided them up by 50, which came out to 1964.6. Without actual years and having just a relative figure, I figured that this could give a quick answers to his question.

Okay, and I think I see where your logic is wrong.

A show could have debuted in 1949 and still been in the 40's, so you're assuming the absolute minimum for each decade, which is gonna get you into trouble. Might make more sense to assign the middle of the era (for example, 1945) as a guesstimate, it'll certainly get you closer.

So, using that, I come up with 1969.6 (which makes sense considering I basically added five years to your numbers), which, considering there are 25 shows before 1970 and 25 after, seems like a much closer guess.
