During the run upto kottu Sinhala font ,I posted a link to an article in "Lakbima" in one of the comments.Lohan has commented on the whole issue in his blog.The article says that since the language of Sinhala news has been degraded ,the minister of cultural affairs is planning on controlling the language used by media,starting with a booklet on how to spell.
I haven't listened to Sinhala TV/Radio programs that much in last couple of years.I can guess what is going on since I have seen what happened after loosening the media control in early 90's.I think the langauge used for Sports ,talk shows or comedy is not appropriate for news.I also belive it's an internal editorial decision of the TV/Radio station.It's upto the Viewers/Listeners to vote using remote control or the small knobs in their TV/Radio sets.
Debates about the langauge changes due to Electronic media is not unique to Sri Lanka.Shepard Smith who has an hour long news show (runup to O'Reilly show at 8 PM EST)on FOX News uses a different kind of language.You can check the transcript of a documentary here or just google.
What's important of this whole issue is that the attitude in Sri Lanka about government control.The Language ,Religion or what date of the month you can get wasted should be controlled by the government!Seriously folks, this is a government who could not protect it's head of state(1 prime minister and 1 president killed.One president lost an eye),Couldn't balance a budget(last balanced budget is 1954 or something) and still couldn't build a highway connecting the capital and airport after 30 years of trying (just 20 miles!Started 1975 or something).What makes you think that the government is capable of forcing you to use correct "Na" or "La" in words?
