1) 'CSI: NY'
This is the most blatant connection. At least one member of the NYC CSI team can be seen outside the Thompson Hotel after a man jumped to his death. It doesn't have to be any particular character from the CBS show; a lot more people would be working in that department besides the six or seven we'd see on a weekly basis.
2) The 'Law & Order' franchise
The New York Sentinel is a paper modeled on the New York Times style, a rival to the NY Ledger which is more of a tabloid paper. If I remember correctly, it shows up in the later years for the opening credits of 'Murder, She Wrote' once Jessica Fletcher moved to Manhattan, but I can't be sure on that. However, it did appear in an episode of the series where it sported a tabloid style of its own. (It must have been a temporary experiment to increase sales.)
3) Honda Civic commercial, "The Prize"
As far as I can tell, Crunchy-O's is a fictional cereal. (The more healthy-oriented Early Harvest may be a fiction cereal as well.) But it was used in a blipvert for the Honda Civic and the giant version of the cereal box doesn't give any indication of a manufacturer's name (Arnold's Acres?), which I think would have been verboten if there was a product placement crossover.
