  6. 1888 Edison introduces an electric motor-driven phonograph.

  7. 1895 Marconi successfully experiments with his wireless telegraphy system in Italy, leading to the first transatlantic signals from Poldhu, Cornwall, UK to St. John's, Newfoundland in 1901.

  8. 1898 ValdemarPoulsen patents his "Telegraphone," recording magnetically on steel wire.
