Today in History – December 6, 1877 - Thomas Edison made the first recording of a human voice, singing “Mary had a Little Lamb,” on his tinfoil “talking machine”, the phonograph. The phonograph would ultimately lay the groundwork for future generations of audio recording and playing technologies such as the juke box, compact discs and digital audio players, like the iPod. See Michael Smith’s November 21 “Today in History” blog on Edison and the release of Toy Story – the first full-length computer animated movie.

Also today in 1768, first edition of “Encyclopedia Britannica” published. It is the oldest English-language encyclopedia still published in print form. As with most encyclopledias today, it is also available online. Although considered a quality resource, it is having a hard time competing with other online research sources, including the free online Wikipedia.
