CBS News Sunday Morning: Historian discusses erosion of importance of penmanship

A story on CBS News Sunday Morning about the erosion of the importance of penmanship in a world filled with computers, cell phone and other technological advances interviews Tamara Plakins Thornton, professor of history, who said handwriting's decline is an old story. "That goes back to the typewriter, actually. It doesn't go back to the computer. We haven't used handwriting the way we used to use handwriting for well over 100 years."
