Perceived Obsolescence
Perceived Obsolescence is when the manufacturer of some product attempts to generate new sales through the marketing of new versions of the same or largely similar product that bear some superficial changes in look. This technique was pioneered by the American Auto companies who discovered that you could get status obsessed people to shell out money for a new car just by changing the colors of the models every year or so.
This marketing psychology also applies to tech gadgets. This is likely why apple periodically introduces colors for its produces.
I would posit that periodic UI "refreshes" that occur every few years across all sorts of commercial software are attempts to generate a feeling of perceived obsolescence in customers and motivate largely unnecessary upgrades.
