Penetration rates of major consumer products in U.S. Households

  1. Establish a measure of penetration rate and rank order the top five appliances for penetration into U.S. households.
  2. What time did it take each appliance to successfully penetrate the U.S. market?
  3. Make as many interesting observations (sociological, political, or otherwise) as you can from the graph.
  4. Identify historical occurences that may be associated with features of the curves and speculate on the possible connections.
