Consumed with uncertainty
Not wanting to be a corporate stooge, but isn't the point of a logo its simplicity and instant recognition factor? Hence a logo being amenable to toddlers. Take today's trip to the Odeon with my six year-old, taking in Robots along the way, as a case in point. Some of the heavily trailed movies beforehand provoked instant recognition, as did a few of the products, including an omnipresent dog food commercial based on Mission Impossible, which comes on every time I take the Princess to the pictures. But one reason some commercials worked better than others was that they were based on strong 'brands' already: thus Ice Age 2 had its popular predecessor to draw upon. If kids didn't like the original, brand recognition would prompt revulsion.
Perhaps it's a good time for parents to dig their heels in and say no episodically, or at least make their offspring earn the cash to fritter away on popcorn, Robots toys - we got 'Bigweld' a.k.a. Mel Brooks - and Magic Roundabout masks.
