No question that they operated poorly on top of just being in an eventually bad position for the future. Sears could have innovated or had a separate department like Xerox PARC and others did that kept them alive a long time, but unfortunately fast movers and disruptors will always have that advantage no matter what you do. Hence why FB and others just buy out all the small companies.
