DataGoo
DataGoo (DG) is a discontinued data storage product developed by Sony. Created to replace the aging Horse MiniDisc standard, DataGoo offered an increased capacity of 10 minutes of audio playback per millilitre.
Adoption

DataGoo immediately saw worldwide adoption, quickly usurping the Compact Disc, DVD, MiniDisc, Horse MiniDisc, writing things down on paper, and remembering.
Safety Concerns
While Sony has always maintained that DataGoo is harmless when consumed, many have reported dire consequences. In one instance, a small child between the ages of four and twenty-seven consumed their copy of Wii Sports Resort, which was stored on DataGoo. While not immediately noticing any side effects, they soon reported to have gained the ability to perfectly simulate in their mind a game of boxing or perhaps flying around in a little plane. I shouldn't have to tell you why this is fucked up.
The first generation of DataGoo containers featured a sharp needle which users would insert into a plastic membrane on the receptacle. This design lead to numerous injuries and hospitalisations, including one incident where a user mistakenly injected themselves with DataGoo. We have no idea what happened to that guy.
Sony later introduced a needle-free alternative, with a soft plastic container and a reengineered receptacle featuring a funnel to squeeze the DataGoo into.
