Maybe the whole (TV-watching) world did become aware.
If so, how do you model that? Frequency jumps from
zero to one in a single instant? How could you fit a
contagion trajectory on that? You need some kind of
sigmoid curve to appear from out of your data, at
least the hint of one, in order to justify any
assertion that a contagion-like mechanism is involved.
