The Missouri-based National Audio Company, reports Ars Technica, is sweeping up in a category that our future-looking selves might twenty years ago have imagined would be dead and buried in the year 2015: making and selling audiocassettes. There are fewer and fewer competitors in the tape-making business, but NAC still has a healthy market for cassettes -- in October, the company noted "a 31 percent increase in order volume over the previous year." From the article: [Company president Steve Stepp] said that as his competitors began bailing out of the cassette business once CDs came to prominence, NAC started buying up their machinery. “It would have been incredibly expensive 30 to 35 years ago when [cassette manufacturing machines] were new on the market, but when our competitors bailed out of the business and started making CDs, we went round the country and bought [them] out," he said. Some artists are still releasing music on tape, but about 70 percent of what the company sells is blank cassettes; there are an awful lot of tape decks out there; my father alone still buys a few hundred blanks each year.
