Switzerland has an open and free media environment. Articles 16 and 94 of the Swiss Federal Constitution provide the legal basis for freedom of expression and the press. The penal code prohibits racist or anti-Semitic speech. In November, Switzerland's highest court placed a temporary ban on the sale of a book alleging ties between Osama bin Laden's half-brother, a Swiss national, and al-Qaeda terrorists. Large media conglomerates are consolidating the newspaper industry and forcing the closure of small and medium-sized papers. The public Swiss Broadcasting Corporation dominates the radio and television sectors. With some exceptions, market forces generally limit private stations to local and regional broadcasts.
