152@90 was initially released as DVD and Blu-ray limited editions on the 15th May 2016, the sole purpose of which was to raise funds for target charities. Even before release date, both editions had completely sold out through advance reservations.
152@90 is still available, but not on disk.
VOD, or Video on Demand, enables the film to be downloaded to TV or computer, either for rent or to buy. Rent is the lowest cost and gives a 24hr window in which to watch the film as many times as you wish through video streaming. Buy means that you can download the film and keep it to watch anytime - or save it onto a hard drive or disk.
