Development of Creative Commons licenses

["Mario Behling" <mb AT mariobehling.de>]

Hello!

I am new to the list and I am not sure, if this is the right place for this 
post.

I am a photographer and journalist and I was wondering if there is already a 
solution to the following problem.

When I publish content, I normally choose a license, that does not include 
commercial usage. If a commercial enterprise wants to use my work, they 
could pay for it. That is the idea. However, I would not mind if a 
commercial enterprise uses my work, let's say, after five years after the 
initial publishing date. This could increase interest in my work and 
publicity.

Ok, I could just change licenses myself, but it would be nice to be able to 
choose a licensing option, that frees up restrictions (automatically and 
gradually) after some time.

Of course I am not a lawyer. So I am not sure, if this would be possible. 
But, as far as I could see, this would also solve some problems concerning 
licence incompatibilities: If many people would choose such an option, it 
would automatically enhance the compatibility of free content over time.

Thank you for an answer!

Ciao from Berlin!
