The selection of medium (written version vs. visual image) mostly affects the understanding of a theme. This is because the creator could create a detailed explanation using written medium but not with the visual image medium<span>. But, it all depends on the readers' knowledge to interpret the medium itself.</span>
<span>In
the novel _The Hitchhiker’s Guide to the Galaxy_ by Douglas Adams, there exists
a scene where Jeltz communicates to the hitchhikers something over the intercom
system. The message that Jeltz tells the
hitchhikers over the intercom system is that the hitchhikers are actually not
welcomed there.</span>
