38 of those reports were paywalled or blocked to us. Our reading of this outlet is built on the 0 we could open, not on everything it published.
On 11 of those stories, outlets rated left were largely absent from the coverage and NBC San Diego ran the story anyway.
Across the 38 stories of ours where at least three of the reports we listed carried a time, we logged no report earlier than NBC San Diego’s on 3 of them. Overall it filed a median of 14 hours after the earliest report we logged.
Measured 18 September 2026. Last seen in a coverage list 18 September 2026. Ratings pulled 8 September 2026.
Other outlets rated the same way
Publishers carrying the same published leaning as NBC San Diego, also publishing from United States, ordered by how often we have seen them on a story. Sharing a rating is not the same as being alike.
Think this page is wrong?
The leanings above are published by AllSides, Ad Fontes Media and Media Bias/Fact Check, and we republish them rather than make them. If you think one is misapplied, the strongest place to say so is with the organisation that made it, and every verdict here links to their page.
What we are responsible for is everything else: the ownership chain, where NBC San Diego publishes from, which of our stories we have listed it on, and whether we have the right publisher at all. Tell us what is wrong and an editor reads it.
Report something wrong on this page
Anything we correct is written up in the public corrections log. We do not publish reader votes as a rating, because an unattributed rating is the thing this site exists to argue against.
Every rating on this page is a named third party’s published work, republished with its author and, where one exists, a link to it. Our own coverage record is the section we measure ourselves. Neither is a judgement of any individual report: those are scored story by story, and the reasoning is on our methodology page.
