Magazine sales research

Due to magazine sales evidently decreasing over the past years (as shown in the graph below), I decided to conduct some research in order to see if there is a way to ensure my magazine would be successful.

I found a book called 'Marketing Research' , published in 2007, which included sales of the media and magazine industry.
 
It was very helpful in secondary research to see if my idea of creating a special edition magazine would be more successful in terms of sales, due to it having a unique selling point. I found that the research proved that for a particular magazine, owned by Time Inc., managed to sell more copies of the special edition magazine in comparison to their regular issues.

Due to this finding, I have decided to make my magazine a special edition issue to be more successful and interesting to my target audience.
