The recent episode of SBS' 'Running Man' set records with one of its poorest viewership ratings. 

According to the results by Nielsen Korea TV Audience Measurement, '2 Days and 1 Night' took #1 with 15.3% in viewership ratings. The special appearance of actress Han Hyo Joo is assumed to be the reason behind the successful result. Second place went to 'Mask King' with 15.0%, while third went to 'K-Pop Star', which aired its final episode. Both 'Return of the Superman' and 'Real Men' equally placed fourth with 10.8%. Lastly, 'Running Man' recorded only 4.9% and set the second lowest viewership rating of the show's history.

The recent episode featured Girl's Day's Hyeri, and WINNER's Song Min Ho and Nam Tae Hyun as guests. Unfortunately, the appearance of hot idol stars did not have much positive impact on the viewership ratings. Many viewers and experts in media worry that the show might be going downhill. 

'Running Man' has been experiencing unstable viewership ratings ever since the airing of 'Mask King'. Other Sunday variety shows are also kicking in to take viewers' attention, and the competition is continuing to get stronger. Though 'Running Man' is one of the iconic variety shows of Korea, nothing lasts forever. 

Do you think the end of the 'Running Man' might be approaching?
