I think it's extremely important. TV5, TFO and Radio-Canada are some of the examples. People often underestimate the impact of Radio-Canada in official language minority communities where that station becomes almost like community radio.
In addition, discussions are ongoing to create a television network for and by francophones outside Quebec. I have been following the progress of that project with great interest. I cannot comment on this directly, but I can say that, for minority families, access to a media environment at home is very important for maintaining the language.
