The call aims at boosting media literacy in Europe through pursuing innovation and collaboration across media literacy communities within the EU, including by building on and scaling up existing solutions. Innovative strategies are sought, to inform citizens of disinformation and to promote a responsible use of communication channels offered by social media. The tools and activities proposed should directly or indirectly benefit the target group of citizens of all ages lacking media literacy skills and in particular the skills needed to critically evaluate content accessed via social media.
