Halsey has criticised Tumblr for not featuring in the video for its 19th Anniversary video, "I Keep Your Lights On for Years", which she believes is a throwback to her early days on the social media platform. The video, which was released on February 27th, was viewed as a reflection on Tumblr's journey, including the rise of the internet meme and large fandom communities. Halsey, a prominent figure in the alt-pop movement of the 2010s with her debut album "Badlands," was left out of the video. The number of Tumblr users has been declining since mid-2010s, dropping from 400 million blogs in 2013 to less than 200 million users by 2016. Some users believe the early-to-mid 2010s is the time that musicians like Halseys, Lana Del Rey, and Marina Diamandis were prominent figures in the music scene.
