The purchased digital content existed long ago since the iTunes Store was released in 2003, but the situation was very different. Devices are not always connected, streaming is not the main way to access purchased (or subscribed) content, but most are physical media (VHS tape, DVD, CD, or 8 tracks). As content is streamed, stored in the cloud, and available on all devices, ownership of the digital content is much more complicated than purchasing movies, books, albums and purchasing indefinitely.
Twitter articles recently, Anders G da Silva (@ drandersgs) Discovered that three separate movies are gone from his iTunes library. After contacting Apple, he learned that the "content provider" of the movie deleted the content from the iTunes Store in Canada. This means that movies on Apple's servers are no longer available to him. It is warning Apple that it's possible with 7000 terms of service.
Me: Just a little Apple, the three movies I bought disappeared from my iTunes library.
Apple: Oh, they are no longer available. Thank you for purchasing them. Here are two movie rentals!
Me: Wait … what? @ tim_cook When was this accepted? pic.twitter.com/dHJ0 wMS QH 9

This is not the only time that happened in modern times. Small changes like album and movie artwork have changed over the years with iTunes content. Kindle Books has been "updated" to correct mistakes and make minor adjustments. The disadvantage of drawing everything out of the cloud is that nothing is permanent.
When you purchased content (books, movies, or music), you left the store.
