When I look back on decades of technology evolution, I keep bumping on the concept called “playlist.”
This short video clip (taken from my laptop in the office, which explains why the low res ^^) shows you how music has moved from:
(a) compact discs (packaged products) to
(b) tracks (divided into components) to
(c) playlists (virtual, evolving products).
All the fads about service-oriented architecture and business process management and mobility can learn a lil’ something from playlists.
