I would hold your bullish sentiments in check for a moment yet.
Correct me if I'm wrong, but the audience of Coronation Street is largely middle-aged and older women. I'm not being ageist or sexist here when I say that they are not exactly crypto's strongest supporters or key demographic. Sure, any mainstream exposure is good, but this alone will make negligible difference in the long run.
What if the middle-aged and older women are people with power and they seem to be intrigued by the mention of bitcoins which could get them to talk to others of the same age or category of people and this spreads awareness which could intern lead to maybe not a significant portion but a group of people now aware of what bitcoin is. In its simplest form I would call this a form of gossip.
