POW! Entertainment started in 2002. POW! has been public since 2005. Disney has put in over $12 million (probably closer to $15 million) since the beginning of 2010. It's been over 5 years since Disney bought in or started their first look deal.
Edit2: Forgot to say, POW! doesn't have much to show for the amount of time and money they have spent.
Are you saying you will give them 3 to 5 more years?
