Instagram is a social network which, in addition to its original function of sharing photos, has also acquired the function of a business platform for anyone who wants to promote themselves, a product or a service as well as to attract new clients, employees or employers. The world of acting, imminently connected to the media and self-promotion, has been largely affected by Instagram too. The aim of this final thesis is to inquire how, in what ways and with what motives actresses, who are also digital influencers, use the social network of Instagram. For this purpose, an in-depth interview method was conducted and Instagram profiles were analyzed using the content analysis method. The thesis also deals with the comparison of the content ratio of the posts of a private nature with those created in collaboration with brands. It addresses various topics, focuses and the most frequent formats of posts, the scope of the followers and the interaction with the audience. These are just some of the key inquiries of this thesis which tries to determine the connection between the social network with the acting career and how influencing can help actors in their engagements, ratings, media visibility as well as valorizing the merit of acting in itself.
