Aside from the financial pressures of owning a newspaper, Cablevision management has also clashed with the editors of Newsday, according to reports in the New York Times and other media sources last month.
The dispute arose over Newsday's coverage of allegations against a player on the New York Knicks basketball team, which Cablevision also owns.
A spokeswoman was not immediately available to give more details of plans for Newsday's website.
