Control is something that entertainment companies strive for, its what they want more than anything in the world. Specifically, they want to control who sees their content and when they see it, all in the name of combating file sharing. As TorrentFreak points out, however, the tons of effort that these industries put into combating file sharing is wasted, and it would be best for everyone of they just accept that.
People started sharing files with each other – text, games, music – as soon as there was a storage medium you could copy. Originally, this meant the compact cassette which was used for music and programs for the first home computers. Cassette decks at the time had a convenient copy mechanism where you’d insert an original in one slot, a blank tape in another slot, and press a prominent “copy” button to get an analog replica – not perfect, if it was music, but if it was a digital computer file, it would be readable and usable. The one-push copy was even a sales point. Everybody had their circle of friends who contributed to the common collection between them, and we’d always be carrying some copy of something else we anticipated was in demand. People would copy something from you more or less every day. You would copy things from several people pretty much every day.
