If you believe that creativity is a commodity then giving it away is plain stupid. I do not understand what you mean by evolution – yes the technology always evolves but the intellectual process does not.
I have and will do the occasional free pitch with a new client – but I prefer to enter a discussion about the project and talk about how the client and designer should work together as a team – rather than have a beauty pageant to win work every time. Then attempt to persuade them to pay a small fee to the people pitching.
You say every market matures – well I think that developments in our industry is infantilising ours. Low entry point software has enabled many to be able to create mind boggling work at home or from small studios but real world experience, training, mentoring is decreasing.
Work can be turned over quicker and cheaper than ever before clients are thinking less before commissioning work and often gifted designers are turning over 5 times the amount of jobs that they used to survive the lower returns and because the market expects it.
Imagine 20 years ago a client ringing up on a wednesday saying “I need a 2 minute animation by end of play Friday”
Hang on – I’ll book the rostrum, the lab, telecine, oh and I’ll see if I can book 40 animators, cell painters, in-betweeners, character designers in order to turn that over…
Sure those days are gone and so has the money but also so has the client’s ability to think ahead.
