The correct answer is - False.
The immigration indeed influenced the media and its reporting, but it was not in a way that the media was bringing in more knowledge and history of the groups who were/are immigrating to the public.
The media mostly changed in a manner that it was bringing up more facts, or more false information, about the political and economic situation about the countries of origin of the immigrants. Also, it prompted heated debates among the politicians that are pro-immigration and against immigration, thus bringing in to the public only extreme points of views, instead of focusing on information about the culture, background, history of the immigrants.
