Adult Alternative Airplay (also known as Triple A or Triple A Airplay, and formerly Adult Alternative Songs and Triple A Songs) is a record chart currently published by Billboard that ranks the most popular songs on adult album alternative radio stations. The 40-position chart is formulated based on each song's weekly radio spins, as measured by Nielsen Broadcast Data Systems. The earliest incarnation of the chart was first published on January 20, 1996, as a feature in Billboard sister publication Airplay Monitor. In 2006, Airplay Monitor ceased publication after Billboard parent company VNU Media's acquisition of rival radio trade magazine Radio & Records, which then subsequently incorporated Airplay Monitor's Nielsen-based Triple A chart.
Billboard itself began publishing the Triple A chart in the issue dated July 5, 2008 through their Billboard.biz website, appropriating the same airplay data as Radio & Records. Radio & Records closed in June 2009, leaving Billboard as the sole publisher of the chart. In February 2014, the chart's reporting panel was expanded from 23 to 32 stations, including non-commercial reporters for the first time.
Following a re-design of their website, Billboard officially incorporated the history of the Airplay Monitor/Nielsen chart from 1996 to 2008 into their Adult Alternative Songs chart. The Billboard website and its official chart archive now shows the first Adult Alternative Songs chart as having been published on January 20, 1996, with "The World I Know" by Collective Soul as its first number one single. Radio And Records first charted their Adult Alternative chart in the September 22, 1995 issue. It was a 30 position chart, and "Til I Hear It from You" by the Gin Blossoms was the first number one. The current number one song is "My Love" by Florence and the Machine.
