Either by political party, or certain group of individual/ company.
Simple way to check this is keep on browsing this channel along with other during prime time and you will see different set of program or different set of news being telecast.
Mockery of democracy
Its a complete mouth piece of single major political party currently in Nation. Completely biased towards it.
