A Case Study of Technological Whiplash

In 2005 the Bureau of Labor Statistics added a category to the Consumer Expenditure Survey—personal digital audio players. The phenomenal success of Apple's iPod demanded a new expenditure category, and four years after the iPod's introduction in 2001 it took its place in the survey. Alas, it was too late to capture the full arc of spending on new technology in an era of innovation—from zero to THE BIG THING and back to zero.

The first year in which personal digital audio players were included in the Consumer Expenditure Survey was 2005. But 2006 was the first full year of data collection—one year before the category was blown to smithereens by the introduction of the iPhone. The first full year of data collection was also the apparent peak year of household spending on personal digital audio players...

Average household spending on personal digital audio players, 2006 to 2016 (in 2016$)
2006: $20.73 (first full year of data collection and peak spending)
2007: $20.13
2008: $15.12
2009: $14.55
2010: $12.57
2011: $10.98
2012:   $7.75
2013:   $4.87
2014:   $3.07
2015:   $1.83
2016:   $1.76

Average household spending on personal digital audio players fell 92 percent between 2006 and 2016, after adjusting for inflation.

The average household spent more on iPods and their kin in 2006 than it did on a number of other entertainment categories, including bicycles, musical instruments, camping equipment, winter sports equipment, and streamed and downloaded audio and video. By 2016, spending on personal digital audio players was one of the smallest items in the entertainment category.
