<i>Windows Solitaire has ads now. Movie theatres have been showing ads since forever. Cable TV is showing ads.</i><p>Although if I were trying to think of business models that seem to be struggling, those would probably have been among the first examples that came to mind. Windows 10 so far appears to be another Windows Vista&#x2F;8. The movie theatres around here seem to operate under constant fear of closure. We don&#x27;t have a complete equivalent of US cable TV here, but I get the feeling that on-line, on-demand services are threatening that model as well. In each case, I can&#x27;t help suspecting that the degree of customer exploitation&#x2F;price gouging has a lot to do with the waning popularity.
