There is the Cable System and Direct to Home (DTH) has also now been started. We see over TV films, matches, discoveries, advertisement, happenings, speeches, etc. Most of these we see live.
There are so many TV serials which are instructive and humorous and some of them are especially meant for a section of society such as children, women, sportspersons, farmers, students, youth etc. Some serials are quite interesting while others are just boring.
We should not sit too close to the TV set. Some children who sit too close to it get their eyesight weakened. We should also not become addicts to TV. TV should not be watched at the cost of studies.
