Textbook Question
Chapter 40, Problem 40SDP
Over the years, numerous consumer products (such as rotary-dial telephones, analog radio tuners, turntables, and vacuum tubes) have become obsolete or nearly so, while many new products have entered the market. Make two lists: a comprehensive list of obsolete products that you can think of and a list of new products. Comment on the reasons for the changes you observe.
