When you switch on the TV, you see a lot of choices of the channels. Now which one to chose? For this you go around all the TV channels and select the one that you find ok.
When finding for a good channel, I am often disappointed. There are very few channels that show good programs. Some programs are made for the sake of showing programs that have no information or entertainment. Especially the music channels are full of noisy rock type songs that have no rhyme and rhythm and no lyrics. The dramas are inspired by the Indian and western culture, many of which have no story, dialogues or properly directed.
There is just a show of glamour in our TV channels right now and one may not find the entertainment or relaxation from these. So the more there are TV channels the lower is the standard.
