Channels on TV

Have been here in Kigali for few weeks now and once again started to watch some foreign channels coming over the TV and once again began my wondering over channels in our countries.
Why is that our local channels show only about our films and cricket...or if they add anything else it will be some beauty shows or some sports of tennis in other countries...
Why is that our channels can not take some lessons from these channels which exlcusively talk on history,tribes,travels, documentries,etc...Its really surprising me, because our countries have so much of rich culture, history and places of interest and the TV could be used in a better way instead of showing pple running around trees or dancing alone...
Yes I do hear some voices that speaks to say that there are channels which talk on our spirituality...but I guess they have done more damage than what and how spirituality topic should be discussed...What I mean is to talk on Ancient glorious past from every single village and to talk on all those great saints and sages who lived and gave messages from Thiruvalluvar, to 63 Nayanmars to Kabir to Ramakrishna Paramahamsa or Ramana Maharshi or Yogaswami and the rest?
We need to bring their message either through the traditional way of spiritual discourses in temples or in TV/Films...
Yeh I also hear that their message is all the same who is to follow...thats the most important question and our purpose of life...I guess but just hope that channels do bring in such topics at some point of life....
