Anything beyond the boundaries of this ticker of raw measurements depends on some level of narrative, and therefore bias. Even the driest, most unbiased reporting of "what happened" is not immune to selection bias in choosing which events to report.
Ironically, the more that a news organization pretends this purist ideal of unbiased news exists, the more biased it becomes in its effort to hide its natural biases.
In terms of raw signal/noise, a pair of oppositely polarized news organizations are more informative than a single "unbiased" one. I learn more about the "truth" (which is mostly a matter of perception) by reading both Fox and CNN, and comparing the overlaps and differences between them, than I ever could by reading a single "unbiased" source of news in the middle.
