Imagine it's the year 1987. You drag yourself out of bed, ready to face another routine day at the office or school. You head outside to grab the morning paper, quickly flip through the sports scores then head for the entertainment section. And there it is. A huge advertisement in big bold letters: "U2 RELEASING BRAND NEW ALBUM 'THE JOSHUA TREE' TODAY AND IT'S FREE!!!!"
Impossible then but a reality in 2014. Not even Doc Brown with his DeLorean time machine could have seen this one coming.
