Free Light Bulb cite re: predatory pricing

[James Love <love@cptech.org>]

  I received the following message, which made reference to a case
  involving free distribution of light bulbs by an electric utility.  Does
  anyone have a cite for this case?   Jamie

  Microsoft is practicing unfair competition: it browser attempts to
  prevent use of other browser once it is installed; giving "it" away
  freely has been ruled unfair: a Chicago drugstore owner vs Detroit
  Edison, (197x ?)--that power company exchanged spent light bulbs for new
  for free to its customers.
