Objectivity in journalism is a lost concept. The way we see news and even facts have changed drastically over time. In this highly subjective media scenario, party-owned newspapers are the most biased, or heavily biased, to borrow a term from solid-state electronics.
Every news is twisted, tilted, or blown out of proportion. Every grain of truth is slanted, till the whole news shifts to left or right, according to the political party associated with the paper. While it is okay for a newspaper to have a perspective, red or saffron or green tinted glasses are an absolute no-no in journalism.
