A co-ed group, also known as a coed group,[1] mixed-gender group[2] or mixed-sex group,[3] is a vocal group that includes both male and female singers,[4] usually in their teenage years or in their twenties.[5]
Historically, co-ed groups have not been as common in pop music as girl groups and boy groups.[1][2][6] Music industry pundits have pointed out that such groups are difficult to market to the typical target demographic of teen pop acts, namely pre-teen and teen girls. According to music writer Jake Austen, girl groups and boy group appeal to young girls in distinct ways, with girl groups marketed as role models and boy groups marketed as objects of desire, and mixing the two is "unnecessarily confusing".[2] Slate's Dann Halem echoed this sentiment, adding that "it's hard to croon convincingly about the pop world's staple subject—teen-age yearning and heartache—if you're harmonizing with the object of your affection."[1]
