About 사건짱
Kim Soo-hwan, who runs the Korean YouTube channel 사건짱 (@sageonjjang), presents himself as a former police detective who now works as a private investigator. The channel publishes long-form case breakdowns of Korean crimes, along with occasional live streams and talk segments, typically at a few uploads per quarter. Viewers appear to be mainly Korean adults interested in true crime, criminal justice and private investigation; these audience figures are estimates based on the content.
The channel shows no sponsorships in its recent uploads. Based on a median of about 830 views per video, the estimated rate is $20 to $30 per sponsored video, which corresponds to a CPM of roughly $20 to $35 per 1,000 views. Paid social ad CPMs typically run $10 to $30, so the cost is comparable but reaches a narrower audience.
This channel suits Korean brands in security, legal services or consumer protection who want a serious, trust-focused context. It is less suitable for entertainment or family-oriented products.
