History
The Adult Top 40 chart was formed following a split of the "Hot Adult Contemporary" chart due to the growing emergence of Adult Top 40 radio stations in the 1990s. These stations played a wider variety of artists and saw a faster turnover of songs compared to traditional adult contemporary radio. Songs by modern rock, dance, and R&B artists were mixed in with acts more closely associated with adult contemporary. According to Billboard, splitting the chart "better reflect[s] the music being played on adult contemporary and adult/top 40 stations."
