It shouldn’t come as a surprise that anime DVDs aren’t selling like they used to. Sales are low enough that some companies have considered abandoning the 24-year-old format. Others already have. When responding to fan questions on Twitter, Discotek Media revealed that they no longer plan to release titles on DVD.
A few people have asked if recently announced titles will come to DVD. They will not.— 💿Discotek Media (@discotekmedia) December 16, 2020
We have no plans for further DVDs. Anime fans simply don't buy them in quantity. Many recent game consoles will play Blu-rays, & stand-alone players have gotten quite affordable.
The lowered cost of Blu-ray players and the advantages of the technology — “more episodes per disc, potentially higher quality video, and ‘much’ better quality subtitles.” — were given as reasons for their decision.
They cite BoBoBo-Bo Bo-BoBo as a perfect example of this in practice. The Seriously! Complete Series collection contains 76 episodes in English and Japanese and “a nice collection of extras” on two discs.
