Yesterday we tried to answer the question, why are most records 12 inches across? Why are others seven inches?
Our post prompted an email from the ever-thoughtful Sam Brylawski, who was quoted in the story and who also was interviewed on Talk of the Nation yesterday about the Library of Congress study he co-authored, titled "The State of Recorded Sound Preservation in the United States: A National Legacy at Risk in the Digital Age."
In his email Sam offered these additional facts that did not make it into our story:
"RCA's 45 (1949) was a response to Columbia's LP, which debuted a year earlier. However, RCA Victor launched a 12-inch "long-playing" 33-1/3 disc in 1931 or so. It flopped terribly for many reasons. Edison, too, experimented with a long-playing disc, in 1926."
And a correction to the apparently complicated relationship between phonograph pioneer Emile Berliner and his engineer Eldridge R. Johnson:
"Johnson never really left Berliner. Injunctions put Berliner out of business and Johnson set up business with Berliner as a stockholder. I suspect Johnson resented paying Berliner royalties for old patents that Johnson had improved so significantly..."
Mr. Brylawski concluded his email with a question:
"So, let's see how long it takes for you to be asked, Does a CD really hold 70 minutes because a Sony executive said, 'make it long enough to hold Beethoven's 9th'?"
Your turn to answer. Does it? Did he?
