Languages of Catalonia
The main cause of Spanish and Catalan social bilingualism in modern Catalonia was large-scale migration from the rest of Spain during the 20th century, as Catalonia started a significant industrialization which demanded an increased workforce from elsewhere. Spanish has historically been spoken among a minority of civil servants born in other regions in Spain and among segments of the wealthiest bourgeoisie. Spanish has also been spoken as a second language by most Catalans, as it has been the only official language over long periods since the eighteenth century.
Telemadrid
Telemadrid caused another big controversy in April 2007, when it aired a documentary called "Ciudadanos de segunda" (Second-class Citizens), which claimed that the Spanish language and the people who speak it were being persecuted in Catalonia in favor of the Catalan Language. This documentary caused outrage in Catalonia's political spheres. Josep Piqué, the leader of the Catalan branch of the Pardido Popular, said that the documentary didn't represent the reality of Catalonia. Meanwhile, the independentist Catalan party Esquerra Republicana de Catalunya demanded that the Generalitat de Catalunya respond to Telemadrid judicially, to no avail. local non-nationalist political parties such as Ciutadans de Catalunya, however, stated that the documentary reflected was largely accurate.
