In March 2010, mastering engineer Ian Shepherd organised the first Dynamic Range Day, a day of online activity intended to raise awareness of the issue and promote the idea that "Dynamic music sounds better". The day was a success and its follow-ups in the following years have built on this, gaining industry support from companies like SSL, Bowers & Wilkins, TC Electronic and Shure as well as engineers like Bob Ludwig, Guy Massey and Steve Lillywhite. Shepherd cites research showing there is no connection between sales and loudness, and that people prefer more dynamic music. He also argues that file-based loudness normalization will eventually render the war irrelevant.
