simple things like Amazon's patent for reselling ebook licences (bound to have an impact on ebook sales especially of lead titles if it were ever to be put into practice) or like discovering that despite having a great product your brand just doesn't resonate with consumers beyond your core audience and hence you lose a bundle of cash trying to sell them tablets or realizing that your

game in which trajectory considerations are a more important aspect of gameplay
than would normally be considered cool and various music video fads from Gangnam Style to Harlem Shake.
