Quick: what would you call a business whose apathetic, listless — and sometimes irate — customers are starting to walk away, whose former blockbuster is becoming today’s lower and lower margin snoozer, whose most promising firebrands would rather eat a pound of plutonium than obey the conventional wisdom, and whose future is openly questioned by its own tribal elders? I’d call it a business for whom the bell of crisis is tolling the zero hour.
