The Fair Trade Commission conducted a three-week on-the-spot inspection on Google Korea to confirm allegations of abusing its power against local game makers.
According to the FTC, the agency recently visited Google Korea's headquarters in Gangnam-gu, Seoul and conducted intensive field investigations for about three weeks.
The FTC's on-site investigation is conducted to secure evidence on cases where suspicions have been found. The FTC conducted an unprecedented three-week investigation.
The FTC conducted a survey and field investigation on local game makers in April and targeted Google directly this time.
Google is accused of abusing market power in the mobile game platform market called the App Market.
Google, which accounts for 61 percent of the domestic app market, pressured game makers to release games only in their app market.
Google Play accounts for 61 percent of the Korean app market, 25 percent of Apple App Store, and 12 percent of the one store created by Naver and three domestic telecommunication companies (SK Telecom, KT, and LG Uplus).
The abuse of Google's grip on the market is controversial worldwide. Google was fined 5.6 trillion won by the European Union (EU) fair trade authorities last month.
