IBM viewed this tech seriously enough to be marketing it to the public in 2006. It wasn't a "Hey, we're making this." ad but more of an, "We're cool because we're working on this, sorta maybe." ad.

14 years later, it's still vaporware. There are a lot of fairly tough problems that need to be solved to make it work. Today, Amazon is probably better positioned to sucker/bully retailers into adopting their solution than IBM is. It remains to be seen if they can actually pull off the tech side of things though. IBM is not a company that's easy to laugh at.
