So much fail in this post.
You realize ~28 million people watched this game right? And it was a game between the AFL and NFL right?
28 million is a
horribly tiny share in the era of 3 Networks on TV when success was determined by some 100mil+ viewers per time slot.
Yeah, 28 million is
today defined as "success," but back when there was no such thing as cable, programs were axed if they showed less than 30 or 40% ratings per time slot.
So yes--at the time of the first Superbowl, it was not a very popular sport and was easily dwarfed by baseball in popularity. I mean, that's why the idea of the "Superbowl" was cocked up in the first place: to try and get people to watch football.
While Grandpa's comment is ironic in retrospect, it was accurate for the time:

EDIT: I'm starting to look up some numbers for comparison. it looks like my 100mil is "a bit off"
A decade prior to the first Superbowl, I Love Lucy--top series in 4 out of 6 seasons, and never lower than 3rd place, drew an average of 40mil viewers--this compared to Eisenhower's inauguration which drew 29 million the year that Lucy debuted.

I need to get into the 60s, because I'm not sure what the adoption rate of TV and viewership was 10 years after those numbers. I just recall reading some article about the major news networks--why cable news networks now dominate over broadcast, but with ratings that are a fifth of what was required to sustain them back before cable. (I mean, obvious when you go from 3-4 channels to dozens to hundreds over the years)
Also, on the NPR broadcast about this NFl network re-broadcast, it was mentioned that the study tossed out the source tape because they assumed that no one would care about it. On top of the fact that pro football wasn't all that popular at the time, that suggests to me that it had a very low viewership for the time.
granted, for pro football, it was probably the most-watched game they had ever broadcast up until that time. So of course it would be a qualified success from an NFL/AFL perspective.
