Park Bo-gum in "Sunkist Cocktail" commercial
TV drama “Reply 1988,” which ended Saturday with a huge nationwide following, not only brought popularity to its cast but also proved its cash power in terms of commercials.
TV commercials slotted alongside the hit drama on cable network tvN cost close to 12.5 million won ($10,000), according to Joy New 24. The price is the most expensive for commercials on Korean television, which air before MBC’s variety show “Infinite Challenge” every Saturday evening.
Commercials for cable network programs have lower price rates than those on broadcast channels MBC, KBS and SBS. But “Reply 1988” became so popular that its commercials became as expensive as the prime shows on the broadcast networks.
