Trivia: What music device did Philips introduce at the Berlin Radio Show in 1963?
Vinyl records
The Walkman
Two-spool cassettes
Headphones
The correct answer is Two-spool cassettes
So why is this answer correct? : The two-spool cassette enjoyed a short stint as the most popular music medium in the U.S. from the 1960s until the ’90s, sandwiched between the reign of vinyl records and the rise of CDs. The peak of their success was in the ’80s, when the Walkman was invented, giving cassettes a more versatile use than the less-portable vinyl record.
