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.
