RIDI recorded 203.7 billion won in consolidated sales in 2021, a 30.9% growth rate compared to the previous year.

Webtoon, web novels get top ranking globally RIDI’s Manta , a global webtoon subscription service, is also continuing its growth by ranking first in 16 countries in North America, Europe, and Asia in the Google Play Store comic app category just over a year after its launch. In particular, RIDI’s mega-hit ‘Under the Oak Tree’ was released as a global webtoon, forming a global fandom beyond Korea. The global fandom of ‘Under the Oak Tree’ continued to the original web novel. As soon as the web novel ‘Under the Oak Tree’ was recently published in English, it climbed to the top list in five countries, including Amazon’s American romance and fantasy category.
