It looks like the CNN clip featuring Stephen Hawking was especially effective—maybe given Hawking’s scientific status and reputation as a genius, and the fact that he’s not seen as a politically polarizing or controversial figure (unlike Elon Musk or PewDiePie).
I don’t think reputation can explain the effectiveness:
The CNBC article had unremarkable effects compared to the other media items, even though it was mostly about Stephen Hawking.
Most of the CNN video (1:20 to the end, 5:51) is an interview with James Barrat, a documentary filmmaker and author.
James Barrat seems to be an excellent orator. I disagree with some of his points in the CNN video, but his presentation is very smooth. Maybe this explains the video’s success.
