People no longer care for stars' Strong Heart?

At least that's what the rating suggests. According to the latest poll from AGB Nielsen Media Research, the most recent episode of SBS' Strong Heart, which aired on November 24th garnered 14.8% viewership, which is 3.4% less than the 18.2% viewership they scored the previous week, on the 17th. Ever since the first episode of Strong Heart aired, the show has been garnering an average of 17~18% viewership each week. This week marks the lowest rating for the show since the first episode aired. However on the same night, KBS 2TV's Sang Sang Plus saw an increase of 3.6% in its viewership, bringing the number up to 9.7% from previous week's 6.1%, suggesting people who were previously tuning into Strong Heart were tuning into Sang Sang Plus on that night. Did the combined presence of Brown Eyed Girls, 2AM and Kara as guests make viewers turn in to Sang Sang Plus instead of Strong Heart? Many people are now wondering how Strong Heart will get its viewers back in the upcoming weeks and was it just a one-off thing. But one thing that SBS can take heart in was that Strong Heart remains No.1 among competing programs for Tuesday night.
