KBS2TV's "Happy Sunday: 1 Night 2 Days" will not be airing on July 24th, due to a special broadcast. From 7 - 8:10PM, the "2011 Fina World Swimming Championships - Male 400M Freestyle Finals and Awards" will be shown, thereby interrupting usual broadcast schedules. A producer from KBS commented, "Because of the World Swimming Championships special broadcast, only the first part of KBS Happy Sunday - 'Qualifications of Men' will be aired on that day." Since the hit show will be taking a break, many are anticipating a marked difference in viewer ratings for other programs in that same time slot, particularly with MBC "I Am A Singer", who's been seeing a decrease in ratings after it moved its time slot to the same one as "1 Night 2 Days". "I Am A Singer" will be having a competition episode this Sunday, thereby piquing additional interest. Source: Money Today via Nate
