Chewing gum consumption has fallen to its lowest level in 10 years.
The value of the gum market fell to W210 billion (US$1=W1,030) last year, according to the industry on Wednesday, about two-thirds of the 2011 value.
Gum consumption continued to decline this year. Convenience store chain 7-Eleven saw gum sales fall 4.8 percent from January to June on-year.
Food and confectionery manufacturers say coffee is replacing gum.
