Despite introducing the compact disc, Sony faced challenges in popularizing it amongst everyday listeners. The CDP-101, while embraced by audiophiles, hadn't made significant progress with the general public.
Kozo Ohsone, head of Sony's General Audio Division, presented a small wooden block (13.4 cm wide, 4 cm thick) to his team, setting the size goal for the portable CD player. This ambitious vision, initially met with laughter, spurred engineers to tackle the complex task of shrinking a CD player to a fraction of its original size.
The creation of the D-50, Sony's first portable CD player, proved pivotal. By creating a compact and affordable device, it democratized CD technology and allowed CDs to finally reach mass audiences, significantly impacting the music industry.
In the early 1980s, Sony introduced the compact disc to the world, but many people still preferred their LPs and Compact Cassettes.

Recognizing they needed a more compelling product, Sony developed the D-50—the first portable CD player that helped CDs reach a wider audience.
Kozo Ohsone, head of Sony’s General Audio Division, reportedly walked into a planning meeting holding a small block of wood that was 13.4 cm wide and 4 cm thick. He told his team, “This is the size we’re aiming for,” then challenged them to shrink a CD player into dimensions similar to four stacked CD cases. People laughed initially but understood the seriousness of the task. Designing a small, affordable player was no small feat, yet the idea caught the attention of engineers who were eager to see if it was possible.
