During that time, 19 additional countries and the European Union joined as signatories (Austria, Belgium, Bulgaria, Botswana, Czech Republic, El Salvador, Estonia, Germany, Greece, Guatemala, Honduras, Indonesia, Montenegro, Poland, Qatar, Romania, Slovenia, the United Kingdom, and Zimbabwe).

[4] According to WIPO "the new treaty brings audiovisual performers into the fold of the international copyright framework in a comprehensive way, for the first time", referring to the clauses dedicated to protecting their works on the Internet.

The expanded economic rights give them an opportunity to share the income collected by producers from internationally distributed audiovisual works.

Publicity was provided by the presence and support from several world-famous actors, namely American Meryl Streep, Brazilian Sônia Braga, Chinese Mei Baojiu and Spanish Javier Bardem and Antonio Banderas, who spoke out on several instances endorsing the treaty.

[9] The treaty has been criticized by digital rights and free culture scholars and activists, for giving the actors a monopoly on deciding how their audiovisual performances can be used.

The performers in question no longer have to hold the copyright to their work for that purpose critics claim, it is possible that the new treaty would make it increasingly illegal to use clips from movies, TV series, and other such preferences in mash-ups, remixes, and parodies.

[10] There are fears that this would allow actors and musicians (who are also covered by the treaty) to shut down any such parody or commentary not to their liking, thus infringing on free speech and limiting fair use and similar reuse rights.
