The term "chillwave" was coined in July 2009 on the Hipster Runoff blog by Carles (the pseudonym used by the blog's author) on his accompanying "blog radio" show of the same name. Carles invented the genre name for a host of similarly sounding up-and-coming bands. In August 2009, "hypnagogic pop" was coined by journalist David Keenan to refer to a developing trend of 2000s lo-fi and post-noise music in which artists from varied backgrounds began to engage with elements of cultural nostalgia, childhood memory, and outdated recording technology.
