Not sure why the pessimistic poster is being downvoted. Factoring for repeat viewers, it is sad how little society values scientific achievements. That said, I was up in the wee hours of the morning watching the LHSC start up and probably put more than 20 views on that song. Have ye hope :D
One is little news report about recent scientific finding (that you don't even need to watch since there are tons of other better sources of that) with viral entertainment video, which is specifically made to get as many viewers as possible. These are not of the same type to be compared.
Scientific achievements don't necessarily make for entertaining video content. I'm sure most people would rather read about most scientific achievements (which these days are largely invisible or theoretical) than read a literary translation of Gangnam Style, too.
