Does 'Kouhaku' still need?

'Kouhaku uta gassen' is one of the Japanese famous TV program which broadcasted on new year's eve and many musician sing his or her hit song.Last year was 57th 'Kouhaku'---but its audience rating was so terrible.Especially in Kansai it was 28.5%. I think Japanese people are no longer interested in 'Kouhaku' because its TV structure is boring and young people do not like enka.Also there is K-1 at the same time so young people tend to see it. To keep traditional style is very important of course,but it is aiso needed to change as time changes.
