This paper shows that people remember better to an image if it is inserted directly into a 3D virtual space than if it is inserted into a webpage. In our study 22 participants took part, they had to read articles displayed in the MaxWhere virtual collaboration software. The individuals had to answer some basic questions about the articles and then in the memory test they were asked whether they have seen an advertisement. Half of the participants saw the advertisements in the sidebar of the articles, for the other group it has been inserted directly into the virtual space. A better memory performance was recorded when the image was placed in the virtual space.
