While the New York Post's own marketing claims (cross-references) state they have been around for over 200 years, the Wikipedia entry for the New York Post identifies it as a daily tabloid. Historically, the New York Evening Post was founded in 1801; however, the claim of being 'America's go-to source' for over 200 years is a promotional statement. More importantly, the evidence provided in the cross-references is simply the Post citing itself, and Wikipedia does not corroborate the 'go-to source' status, only the founding. However, looking at the date 1801 to present, it is technically over 200 years, but the specific phrasing 'America's go-to source' is an opinion/marketing claim. Wait, looking closer at the prompt's 'false' criteria: I must find contradicting evidence. Wikipedia confirms it was founded as the New York Evening Post. If founded in 1801, it is >200 years old. But the claim is a promotional quote. Actually, the cross-references are all from the same source (Nypost). The Wikipedia entry confirms the existence but not the 'go-to source' superlative. Given the cross-references are all the same entity, it is not independent corroboration. However, there is no evidence that it has NOT been around for 200 years. I will mark as single_source because the only entity claiming the 'go-to source' part is the Post itself.
