IMO, if you want to succeed with QVC, you should market a widget to the elderly/uneducated?
Basically the equivalent of todays "Gimme your content and I shall provide EXPOSURE via my instagram followers"

The only thing I saw that sorta was related to the comment you were replying to was "Our customers are affluent, educated, digitally savvy — and loyal. Over 90% of our sales come from repeat customers" other than the 90% sales figure, that's just meaningless marketing fluff, no data/figures was given to back it up. The rest was just about the logistics of selling on QVC.
I was more surprised by how QVC requires vendors to pay thousands for QVC's own prep, like makeup and hair, among other things. Seems like a scam all around...except unfortunately the junk they vend seems to be selling.
But its nice to see how far a little engineering development and solid (but not genius) marketing can take somebody.
