Current/Original Marketer: Telebrands
Original Hit Year: 1999 (No. 13 on the JW Annual)
Note: Thanks to George S., this post has been updated to include missing information.
The site is already down, so no need for a prediction. I couldn't even find a good image online to use for this posting, so I had to use a photo of the original packaging. In fact, the only reason I'm writing about the product is for future research.
For the record, this is the third failed attempt at marketing a shelf solution I've noted in recent years. IdeaVillage/Sullivan tried a shelf with a built-in level called Perfect Shelf in 2009. Several years before that (2002), Telebrands tested a lighted corner shelf called Bright Shelf (HT: George S.). In any case, it seems corner shelves are another relic of DRTV's "Golden Age" that can't be brought back.
