In the cultural sphere, there are many books, plays, and songs being written or produced in the Punjabi-language in Pakistan. Until the 1970s, there were a large number of Punjabi-language films being produced by the Lollywood film industry, however since then Urdu has become a much more dominant language in film production. Additionally, television channels in Punjab Province (centred on the Lahore area) are broadcast in Urdu. The preeminence of Urdu in both broadcasting and the Lollywood film industry is seen by critics as being detrimental to the health of the language.
