The Chicken and the Egg
It is inarguable that the quality of magnetically recorded sound has improved immeasurably in the last 101 years. 101 years? Yes, according to a fascinating account in the May 1988 issue of the <I>Journal of the Audio Engineering Society</I>, it was in 1888 that the Cincinnatti-based engineer Oberlin Smith experimented with recording information on steel wire by drawing it across the corner of an electromagnet around which a coil had been wound. Smith only carried out experiments without producing a practical recording system, and it wasn't until 1898 that the Dane, Valdemar Poulsen, was granted a German patent for a "Method for the reception of news, signals, and the like."
