kdrama1-9, Exercise 2: Crash Landing on You

Model answer:

It aired on tvN from 14 December 2019 to 16 February 2020 (16 episodes); in South Korea it was livestreamed first on TVING, and Netflix acquired exclusive distribution rights in over 190 countries. In Asia, English-speaking regions and Latin America, episodes appeared on Netflix right after each Korean broadcast; in Japan and Europe the full series was released on 16 February 2020.

Budget: approximately US$20 million (attributed in the article to a business newspaper). Filming: Switzerland (Interlaken and the Jungfrau region), Mongolia (standing in for Pyongyang) and South Korea (DMZ scenes on Jeju Island).

Ratings: the lead gives the finale at 21.7 percent nationwide, the highest-rated drama in tvN's history at the time; the episode table lists viewers in millions (1.508 million for episode 1, 6.337 million for episode 16). They differ because one is a rating (a share of households) and the other a count of viewers; the page does not convert between them.
