Recital 61 In recent years, the functioning of the online content market has gained in complexity. Online content-sharing services providing access to a large amount of copyright-protected content uploaded by their users have become a main source of access to content online. Online services are a means of providing wider access to cultural and creative works and offer great opportunities for cultural and creative industries to develop new business models. However, although they enable diversity and ease of access to content, they also generate challenges when copyright-protected content is uploaded without prior authorisation from rightholders. Legal uncertainty exists as to whether the providers of such services engage in copyright-relevant acts, and need to obtain authorisation from rightholders for content uploaded by their users who do not hold the relevant rights in the uploaded content, without prejudice to the application of exceptions and limitations provided for in Union law. That uncertainty affects the ability of rightholders to determine whether, and under which conditions, their works and other subject matter are used, as well as their ability to obtain appropriate remuneration for such use. It is therefore important to foster the development of the licensing market between rightholders and online content-sharing service providers. Those licensing agreements should be fair and keep a reasonable balance between both parties. Rightholders should receive appropriate remuneration for the use of their works or other subject matter. However, as contractual freedom should not be affected by those provisions, rightholders should not be obliged to give an authorisation or to conclude licensing agreements.
