kwebtoon1-1, Exercise 3: Figures and causes

Model answer (any two figures):

- $5.91 billion: is it global or U.S. only (the two articles disagree), for what year, and from what source?
- KR₩420 billion (US$368 million): what year is "currently", and does it include derivatives such as adaptations?
- A quarter of all book sales: which year, and which source (a Bloomberg writer is named, no date)?
- 6.2 million daily users vs 180 million monthly users: different measures (daily vs monthly, Korea vs worldwide), so not comparable.

Two causes for comics moving online: (1) the Webtoon (platform) article says that posting comic content for free caused the book and comic industry to rapidly collapse; (2) the Manhwa article says most manhwa moved online because of the economic collapse South Korea experienced at the end of the millennium. Neither is sourced in the passages read, and the two are not the same cause.
