Length of copyright
Copyright subsists for a variety of lengths in different jurisdictions. The length of the term can depend on several factors, including the type of work (e.g. musical composition or novel), whether the work has been published or not, and whether the work was created by an individual or a corporation. In most of the world, the default length of copyright is the life of the author plus either 50 or 70 years. In the United States, the term for most existing works is a fixed number of years after the date of creation or publication. In most countries (for example, the United States and the United Kingdom) copyright expires at the end of the calendar year in question.
The length and requirements for copyright duration are subject to change by legislation, and since the early 20th century there have been a number of adjustments made in various countries, which can make determining the copyright duration in a given country difficult. For example, the United States used to require copyrights to be renewed after 28 years to stay in force, and formerly required a copyright notice upon first publication to gain coverage. In Italy and France, there were post-wartime extensions that could increase the term by approximately six years in Italy and up to about 14 in France. Many countries have extended the length of their copyright terms (sometimes retroactively). International treaties, like the Berne Convention, establish minimum terms for copyrights, but these only apply to the signatory countries, and individual countries may grant longer terms than those set out in a treaty.
Copyright term and the public domain
The extension of copyright term, imposes tangible restrictions on the public domain. For instance, scholar Neil Netanel argued that Copyright Term Extension Act 1998 prevented the entering of works central to cultural heritage of the US into the public domain. He argued, culturally important dissemination, recasting, or incorporation into new expression is prevented due "to the copyright holder's veto". As examples he gave the adaption of the plot from novels such as The Great Gatsby and Peter Pan, the refashion of characters like Mickey Mouse, or the use Tin Pan Alley songs like "Let's Do It (Let's Fall in Love)" for documentaries about the Great Depression.
Copyright term and orphan works
For the millions of older copyrighted works of less enduring popularity, it is difficult, or impossible, to trace the copyright ownership and determine who holds the particular rights that would have to be licensed for the use of the work. The problem of such orphan works stems from the extension of copyright term and the lack of requirement for the copyright owner to renew or register their copyright.
Reception and discussion
Discussions about the optimal length of the copyright term (e.g. regarding the copyrights incentive for creative production) is a significant part of public and scientific discourse and reception.
On of the earlier and often cited positions is from the British politician Thomas Babington Macaulay who argued in a 1841 speech in the House of Commons that copyright is a monopoly and as such has generally negative effects on society.
In 2009, a paper by Rufus Pollock of University of Cambridge scientifically quantified the optimal copyright term length at 15 years, significantly shorter than any currently existing copyright term, via an economical model with empirically-estimable parameters.
In 2013 scholar Petra Moser concluded in a paper on the impact of the copyright extension on the British Copyright Act of 1814 that "longer copyrights raise the costs of accessing intellectual assets for consumers and other firms, which may discourage the diffusion of knowledge and decelerate the pace of cumulative innovation and learning-by-doing."
In 2014 a Rock, Paper, Shotgun article about the existence of orphaned classical video games and the suggestion of letting them enter the public domain after 20 years, raised a controversial public debate about copyright terms and public domain between game industry veterans John Walker, George Broussard, and Steve Gaynor.
A March 2015 published Journal of Artificial Societies and Social Simulation paper, analysed with a simulated model the relationship of scientific knowledge creation to copyright term length and concluded a decreased knowledge production on copyright term increases for the analysed context.

The optimal level for copyright has been a matter for extensive debate over the last decade. Using a parsimonious theoretical model this paper contributes several new results of relevance to this debate. In particular we demonstrate that (a) optimal copyright is likely to fall as the production costs of `originals' decline (for example as a result of digitization) (b) technological change which reduces costs of production may imply a decrease or a decrease in optimal levels of protection (this contrasts with a large number of commentators, particularly in the copyright industries, who have argued that such change necessitates increases in protection) (c) the optimal level of copyright will, in general, fall over time as the stock of work increases.

The optimal term of copyright has been a matter for extensive debate over the last decade. Based on a novel approach we derive an explicit formula which characterises the optimal term as a function of a few key and, most importantly, empirically-estimable parameters. Using existing data on recordings and books we obtain a point estimate of around 15 years for optimal copyright term with a 99% confidence interval extending up to 38 years. This is substantially shorter than any current copyright term and implies that existing terms are too long.
