messages.content: GfK (www.gfk.it), a European custom marketing research company, conducted a two-year, two-part study
  to determine the new trends in European youth and culture—what matters to European teenagers, and how
  international marketers should approach them. Exploratory research in the form of focus groups was
  conducted first to identify issues that are salient to European youth. The issues identified in focus groups
  were quantified by conducting a descriptive longitudinal survey. The survey was conducted in two parts
  spanning 16 different European countries, including Denmark, Norway, Sweden, the United Kingdom,
  Germany, Italy, Spain, and France, among others.
  In each country, four groups of respondents were selected; 14–16-year-old girls, 14–16-year-old boys,
  17–20-year-old girls, and 17–20-year-old boys. A descriptive survey was designed and administered in
  personal, face-to-face settings. Given the European youth culture, it was felt that the teens would feel
  more comfortable and be able to provide more candid responses in a personal setting. A total of 523 young
  people participated. Two years later, the same people were contacted in 9 of the 16 countries, with a total of
  305 people participating.
  The results showed that tastes and opinions of teenagers in Europe have been changing dramatically
  over the past few years and particularly during the last two years. It was discovered that European teens
  did not trust big companies. The concept of home included not only the family and actual
  home dwelling, but a sense of belonging and community, especially with friends. It is a symbol of
  coziness and warmth. The European teens did not see their families much during the week. Instead,
  friends filled this home function. Finally, they did put a lot of stock in a brand that has been around for
  a long time, feeling that if the brand has proven its existence over time, it must be good and worthy
  of its long stay.
  
  The results proved very beneficial for McDonald’s (www.mcdonalds.com) in developing their inter-
  national advertising aimed at this market. McDonald’s new campaign did not focus on its big-company
  
  status but localized its advertising to make it seem to be the local hamburger hangout joint for teens.
  Meeting up with friends at the local McDonald’s made the McDonald’s “home.” It appeared to be
  fun, and the teens wanted to be there. Additionally, McDonald’s focused on the longevity and stability
  of the brand. It will always be around as a fun place where teens can hang out with their friends and
  have fun for a low price. The campaign resulted in increased market share in the lucrative European
  teenage market. As of 2009, McDonald’s derived more than 35 percent of its total sales from
  Europe.
