Why wouldn't he continue when QVC and HSN studios combine?
As is usually mentioned by the hosts when he is on HSN, his products garner the most FIVE STAR reviews of any vendor they present on HSN. He has thousands and thousands of positive reviews, where others may only have hundreds or dozens of reviews.
The people who use his products are passionate and he has shown over and over that he is willing to change his products when people have suggestions. And he isn't pushy. He frequently indicates that even if you don't purchase his products, there are certain things to know about taking certain alternative supplements, like the timing (with or without food), etc.
Even if there is a presentation of something I don't need, I continue to learn about health thru him. He explains things simply and is easy to understand. He does not talk fast, which I appreciate. And, most importantly, the HSN hosts allow him to do most of the talking.
