One of my idea was establish a copyright renew system in which first year is free, then for second year the right holder will pay $1 to retain the rights, third year pay $2, fourth year pay $4, fifth year pay $8... which follows the power of 2. If they cannot pay for next year then the copyright will fall into public domain (or allows more restrictive form of non-commercial). Most of the worthless stuff will expire at around 10-15 years. Then around 35-40 years for big works that generate tons of revenue if they can pay that amount.
