The Economist Editorial goes for 14 years copyright

A really good idea! The Economist also says that the digital revolution also has lowered the cost on production.

"Over the past 50 years, however, that balance has shifted. Largely thanks to the entertainment industry’s lawyers and lobbyists, copyright’s scope and duration have vastly increased. In America, copyright holders get 95 years’ protection as a result of an extension granted in 1998, derided by critics as the “Mickey Mouse Protection Act”. They are now calling for even greater protection, and there have been efforts to introduce similar terms in Europe. Such arguments should be resisted: it is time to tip the balance back."
