The Economist’s Prospero blog explains it’s millenials, not baby boomers, who are driving the boom in vinyl sales:

Many consider nostalgia the driving force behind this uptick. Turntables are cheap and easy to get hold of (a Crosley costs less than $100 on Amazon) and so furnish baby boomers with a good excuse to dust off what remains of their collection, and expand it further. But data show that this isn’t a sufficient explanation: nearly 50% of vinyl customers are 35 or younger, according to ICM. Indeed, it is 25-35 year-olds who are the most voracious demographic, taking home 33% (by comparison, 45-54 year-olds are responsible for only 18% of sales). Millennials might like to carry their favourite songs around with them and discover new artists via streaming apps, but they also want to collect that music in album form.

The key word to understand when it comes to records is experience.

We’re physical animals and we enjoy physical activities, particularly in a world getting more and more digital and virtual.
