The function of QVC hosts as "sales people" is diminishing rapidly with each passing week.
The vast majority of Qurate's 9 million customers no longer need to watch a television program. They simply go the app or website, as they would with Macy's or J Crew or Pottery Barn or any other retail.
The role of the host is now entertainment personality, guiding the buyer to shop online via streaming programs. They will no longer "sell", if in fact they ever did.
Broadcasting is dead, a dinosaur from the 1990s.
