The kitchen shows are my favorites and I watch them whenever they're on, whether live or later. That said, I haven't particularly enjoyed the Wednesday ITKWD show for the past couple of years; they keep trying to make it "new" or "special" or "different," but it all ends up being the same plus a bunch of annoying and unnecessary nonsense (remember when they thought it would be fun and innovative to display the items in drawers and on shelves at the back of the set where you could only see the front of things?).
So as a big fan of all the kitchen shows, I will surprisingly request this: Just cancel the Wednesday night ITKWD show. It doesn't need to be revamped—it needs to go. Keep the four-hour kitchen shows on Saturday and Sunday where you have lots of long-time viewers/customers and just sprinkle a few more hours of kitchen-related shows around the rest of the week as you do with other non-fashion categories.
Having one-hour shows featuring a single brand would be fine, or truly be original and offer kitchen shows with a theme such as "Fall Entertaining" or "Holiday Parties" with special seasonal items or highlights of how to use everyday gadgets for big crowds or unique purposes. The ITKWD "holiday shows" end up being all food, which is not engaging when it happens over and over (and again, I'm someone who buys food, but there are too many food shows).
I think this may be the direction QVC is heading with a Wednesday night show that only has a few kitchen items in it, and it's the right move. There is so much more that could be done to keep viewers or bring in new ones. This approach may re-energize David as well; even he seems bored with the shows at times, so letting him focus on one big show per week with all he wants to give it and then perhaps hosting other categories (I'm sure there are lots of vendors who want David to sell their products with his big fanbase) or just an hour of a show with a kitchen theme every now and then could be a welcome change for everyone.
