  •  A seemingly trivial "wrong time" tech blunder: (7+ / 0-)

    Thomas Edison's long playing disc of 1926. We think of microgroove recording being an advance of the 40's, but it was commercially marketed by Edison in the mid-20's. His 10 inch LP of 1926 had 400 turns per inch--more than a later vinyl LP--and revolved at 80 rpm achieving 12 minutes per side. The 12 inch version played for 20 minutes per side, or about the time of a 33 1/3 rpm 12 inch LP.

    Several things worked against him to make this a flop however, most notably the fragility of the grooves, low volume compared to his standard records, and the advent of electrical recording and the increasing popularity of radio. A ton of r&d money was sunk into this project and in the end it was one of the major causes of his leaving the entertainment record business altogether by late 1929.

    Here. Watch one of these play. (I own ONE of these discs, but this is not mine playing. They are scarcer then hen's teeth and highly prized by collectors):
