In the article titled "Surfer's Up" by Pearl Tesler, the author reveals the emergence of aerial maneuvers in surfing. The author points out that how such aerial maneuvers were ignored by the jury while judging their surfing skills. But lately, the jury have decided to judge the skills of surfers not only on the basis of how long they remain on the waves but by the difficulty level as well.
Therefore, the surfer's response to the trend of aerial maneuvers being incorporated into surfing and surfing competition is relieved and happy. They, now, can show their best moves and give a tough fight to their competitors.
The the commercial you watch on the apple web site, the cheerleaders yell "mac is number one". This is NOT an example of the name calling propaganda technique!
Propaganda are advertisements that promote a product or service. An example would be an ad that promotes one brand of toothpaste over another.
