"Running Man" is not far behind "Dad Where Are We Going."

According to Nielson Korean's viewer ratings, the September 8th SBS "Running Man" episode had a viewership of 13.6%, which is a 2.3% increase from the previous week's 11.3% viewership.

The latest "Running Man" episode's high viewership rating is largely in thanks to all the idol stars that appeared as guests on the show. The episode was a special titled "The Idol King," and starred 14 idol stars, who found synergy with the cast members of the show.

Not only did "Running Man" see a spike in viewership, so did "Barefoot Friends," and the overall viewership for "Good Sunday" jumped from 8.5% to 9.6%.

On the other hand, MBC's "Sunday Night," which is currently number 1 in terms of Sunday entertainment variety programs, has somewhat diminished a bit in popularity. Although "Dad Where Are We Going" still placed number 1 in Sunday entertainment with a viewership of 15.9%, it underwent a decrease from the previous week's record of 17.8%. "Real Men," which took the number 1 last week at 17.9%, also saw a decrease in viewership at 15.7% this week. "Happy Sunday - 1 Night 2 Days" recorded a viewership of 10.5%.
