Whodathunkit! Cassette tapes are still a viable means of distributing new music...in prison that is. A Los Angeles-based company called Pack Central sells new and old music via mail-order to prisoners on cassette because other forms (like CDs) could too easily be turned into deadly weapons.
We'd like to go on record saying that we love the cassette and all its plastic durability. But, as one person notes in the comments of Gizmodo's take on this piece, couldn't you turn a cassette into a shiv as well? Probably. Probably.
