Dig Music digital radio station joined the Triple J family and was relaunched as Double J on 30 April 2014. The new station features both new music and material from Triple J interview and sound archives. Former Triple J announcer Myf Warhurst, who hosted the inaugural shift, said "it's for people who love music, and also love a bit of music history." The station celebrated its 40th anniversary on 16 January 2015 with the seven-hour "Beat The Drum" event at the Domain venue in Sydney.

The majority of performers played a combination of their own music and cover versions, including Sarah Blasko and Paul Dempsey's rendition of Crowded House's "Distant Sun", and The Preatures covering "At First Sight" by The Stems and The Divinyls' "All the Boys in Town". In ratings released in August 2015, Triple J was the highest or equal first in Sydney, Melbourne, Brisbane, Adelaide and Perth in the 25–39 demographic.

In common with other Australian radio stations, Triple J has also gradually increased the amount of talkback content in its programming. There are several reasons for this. Most importantly, it provides an inexpensive and popular source of program content, and also provides the appearance of listener interactivity and involvement. Like many other former 'all music' stations, Triple J has had to respond to the advent of music file-sharing, digital music players, and other digital music innovations, which have drastically reduced listeners' dependence on radio as a means of accessing music. Evolution of programming The evolution of Triple J's programming has always been contentious. In the Double Jay days, commercial stations and conservatives regularly cried foul over the station's free use of expletives on air and
