The compilation anime both streamed on YouTube in Japan on May 15, 2020. The Summer Vacation OVA screened in Japan in July 2019, and was also available for streaming on PlayStation Video and Bandai Channel in the same month.
FUNimation Entertainment streamed the 2013 television series as it aired, and released the series on Blu-ray Disc and DVD in 2015 and 2017 with an English dub.
The various anime are based on the Hyperdimension Neptunia role-playing video games created and developed by Idea Factory. The games are set in the world of Gamindustri, which is divided into four regions/nations which are each ruled by one CPU. Each region is completely different from the others in appearance and atmosphere, with each representing a specific video game console.
