WASHINGTON, Jan. 10 /PRNewswire-USNewswire/ -- Following is the daily "Profile America" feature from the U.S. Census Bureau:
SUNDAY, JANUARY 10: 45 RPM RECORDS
Profile America -- Sunday, January 10th. The sound recording business became more complicated on this day in 1949 -- when RCA unveiled the 45 rpm record. So-called "long-play" recordings, either 10 or 12 inches and turning at 33 rpm, had been around for a few years, but older, 78 rpm technology was still used for recording single musical selections. Seven-inch 45s soon took over the pop single market and were the favorite of teenagers across the country until 8-track tapes and cassettes came along. More recently, CDs have been the standard, but they are giving way quickly to electronic music downloaded to iPods. Nonetheless, Americans still buy about $7.5 billion worth of CDs each year. Profile America is in its 13th year as a public service of the U.S. Census Bureau.
