In their study of two paralympic promotion campaigns, silva and howe found that representations of athletes in the paralympics varied widely and often created controversy. they attributed this to the fact that

Howe and Silva looked at the reception of the two ad campaigns. One was from the United Kingdom for the 2012 Paralympics and the Superatleta ad in Portugal. Both showed the people with disability overcoming great odds to do what they are doing.
