The popularity of male and female groups in Korea has swung both ways in recent years. In the 2013 Billboard ranking,[208] female groups only made up 20 percent of the most viewed K-pop videos with male groups making up 40 percent. However, in the 2014 ranking [209] the popularity swung in the favor of the female pop groups when they gained an additional 16 percent and the male groups fell by 12 percent. Although it appears there are not many co-ed pop groups, male and female groups both take alternating turns in the spotlight as is clear from the results of the 2013 and 2014 rankings.
