The New York Observer, the sharp-tongued chronicler of New York City’s power elite owned by Donald J. Trump’s son-in-law, Jared Kushner, is ceasing its print edition, just shy of its 30th year as a weekly paper.

The issue printed this last Wednesday was the paper’s last, Joseph Meyer, chairman and chief executive of Observer Media, the paper’s parent company, said in an interview on Friday.

The decision will eliminate the use of New York in the paper’s title — its website is Observer.com — and signals an end of an era when The Observer served as a fixture of Manhattan reporting and a training ground for scores of journalists now in senior positions in the media world.

It also comes as newspaper coverage of New York City is being trimmed. The Wall Street Journal will publish its final Greater New York section on Saturday, a result of widespread cuts at the paper. The Daily News, whose staff has already shrunk, announced a new round of layoffs this week. The New York Times is rethinking its own Metro coverage as the paper seeks to lure global audiences.
