I have a saying, paraphrasing The Man With No Name: "when a business forgets what business it is in, that business is a dead business."
For example, Polaroid made their money on instant photography - that was their business. They forgot that, and got the idea they were in the self-developing film business, and so chose to ignore the digital photography business, because it wasn't self-developing film. Kodak moved in, and look where Polariod is now.
...and it sure is about time too. In 2005 a California LEO tasered a man on the street who wasn't resisting, attacking or trying to flee. Without a word of warning, the LEO tasered the man in the arm with two metal darts, delivering a 1,200-volt jolt. What happened next?
