Input: Article: In 1931, RCA Victor launched the first commercially available vinyl long-playing record, marketed as program-transcription discs. These revolutionary discs were designed for playback at 33 13 rpm and pressed on a 30 cm diameter flexible plastic disc, with a duration of about ten minutes playing time per side. RCA Victor's early introduction of a long-play disc was a commercial failure for several reasons including the lack of affordable, reliable consumer playback equipment and consumer wariness during the Great Depression. Because of financial hardships that plagued the recording industry during that period (and RCA's own parched revenues), Victor's long-playing records were discontinued by early 1933.

Now answer this question: How successful was RCA Victor's program-transcription discs?

Output: commercial failure

If any girl became pregnant outside of marriage, her family paid a fine of one cow to the local chief. After a number of years, when the girls had reached a marriageable age, they would perform labour service for the Queen Mother, ending with dancing and feasting.
