I'm not sure the target audience for 60 minutes is that similar to the audience that would care about drone delivery or Cyber Monday so much. Suggesting that Amazon may have intentionally wanted the story aired the day before Cyber Monday seems like a bit of a stretch. Also, the fact that Amazon wants to do drone delivery in the future has been discussed previously, and they still say it's a few years out, so this isn't much of a story to begin with.
