title: Heterogeneity in TV fast food advertisement exposure in South Korea.
abstract: OBJECTIVE
  To assess TV fast food ad exposure in South Korea.
  
  
  METHODS
  We assessed time trends of targeted ratings (licensed from Nielsen Media Research Korea) by household income and education during 2004-2010.
  
  
  RESULTS
  Lower income groups saw more fast food TV ads during the study period. Exposure decreased in all income groups with a bigger income gap in 2010 than in 2004. The relative exposure to local fried chicken franchise TV ads surged from one fifth in 2004 to half of all TV fast food ads seen in 2010 in all socioeconomic status (SES).
  
  
  CONCLUSIONS
  Future studies should assess the link between TV fast ood ad exposure, an important contextual factor for individual food choices, and actual consumption.
