A long time ago, there was a shopping telly service called Home Shopping Club, based in Florida, which later became Home Shopping Network and which then amalgamated with QVC. Anyway, HSC had a counter on the screen that ticked off each sale, as it happened. I wonder if QVC has the same thing going, but out of sight of customers. This would account for the presenters going off track when the ticker is moving fast. Knuckles telling us how 'gobby' her kids are, for e. g. (Gobby mother, equals gobby kids.) But when the ticker slows down, the presenter will start the hard sell and begin shouting, e. g. Anne Dawson in panic mode. Just an idea.
