I don't spend a lot of time on either channel, but I do often watch Beauty Report with Amy Morrison. I'll keep it on in the background while working on the computer. But, they don't usually take up the entire 2 hours on one product, even if it's the TSV. They may show it twice, but not an hour each time. There's almost always a product or two from her bestie, the Beauty Spy lady.
If they're so afraid they're going to miss one veiwer who pops in, why don't they just put the TSV in a little box up in the corner? They could even do that all darn day long when they're not presenting it.
