History

Conventions shifted in the early 1960s, at which point record companies started assigning the song they wanted radio stations to play to side A, as 45 rpm single records ("45s") dominated most markets in terms of cash sales in comparison to albums, which did not fare as well financially. Throughout the decade the industry would slowly shift to an album-driven paradigm for releasing new music; it was not until 1968 that the total production of albums on a unit basis finally surpassed that of singles in the United Kingdom.

Today, with the vast majority of music released and accessed without any physical carrier and predominantly as separate works, the traditional A-side/B-side distinction is obsolete. Nonetheless, some contemporary artists have added on a second track to a single-track release as a metaphorical "B-side" or "bonus track", which can serve as an aesthetic choice as well as a promotional tool.
