We've recently become hooked on TV's Homeland. One of the main characters supposedly grew up listening to Miles Davis, though I confess I'd never heard of him or his music before the TV show.
However, each episode has included a little snippet of his music. I'd not really noticed it before this week when he got a mention from one of the characters, and I used the Shazam app on my iPhone to listen and tell me which track was playing...
Next day I did a Google search and read some online reviews of the album. They were all glowing and, a few buttons later, the album was purchased, downloaded and playing on my iPhone.
In years past I'd never have been able to learn about his music so quickly and effortlessly, and I'd probably not have gone out to buy it specially. By making it so easy and "frictionless" to discover and buy the economy has grown as my bank account has shrunk!
