For the most part, corporate executives are schooled in business, not engineering. They know planning, reorganizing, finance, merging and acquiring, and (maybe) marketing. Their path to success is through doing those things. Initiatives that originate among the engineers have a long wait to see the light of day -if they ever do - because they first have to be championed by one of the aforementioned executives. That's why innovation in larger companies is done by acquiring products and technology from the outside, and usually not by developing ideas from within. The silver lining is that it creates opportunity for smaller companies that are more focused on their customers' needs and the technologies for satisfying them.
