A few examples of products that have become services:
Music: Before you bought a CD, now you have a subscription to Spotify or Apple Music
Transportation products: Before you owned a car (product), now you can pay to go from A to B with services like Uber
Fashion products: Before you owned expensive dresses (product), now you can rent them for usage on services like Rent the Runway
To go deeper in that topic I recommend that you read the wikipedia page about the Sharing Economy.
