Analysis of a Channel 4 Documentary Advert

I have taken into account some of my lecturers points. The 'High on blow' text is more of a tagline, as it is the line used to grab the readers attention. The 'high' and 'blow' have connotations of drug use and therefore relate to the aduience on a popular culture level, also this would excite the reader before they read that the documentary was actually about storms.
      The Channel 4 sign not only serves as an identity tag on the documentary, but also to instantly tell the audience where the program can be found and also, if they are familiar with the channel, give them a hit to the style of the documentary.
