Based on time series analyses of social big data on ‘Merceron’ TV advertising of Oral Contraceptive,
this study investigates patterns of recipients’ cognitive and emotional changes when they are exposed
to the TV advertising then identifies trends of both association and emotion words. We find that
positive associational words regarding Merceron TV advertising appeared in the early stage, then there
was a big upsurge in the volume of critical comments on the content of the advertising ever since May
01, 2015 as the negative opinion of the TV advertising increased. We also find that associational words
not only criticized the content of the advertising but also emphasized the awareness enhancement for
both men and women by comparing that of the male contraceptive products. In analysis of emotional
words, many positive expressions about the content of ads appeared until April 30, 2015, but
overwhelmingly negative emotional words emerged ever since May 1, 2015. The analysis of
associational words shows uneasy feelings about passing responsibility of contraception entirely to
female, and the increasing demand for male contraception instead. Overall, this study suggests some
practical implications for the future production of TV advertisements on gender-sensitive products
like oral contraceptives.
