In what could be the makings of a new Boston Tea Party, NBC affiliate WHDH in Boston said Thursday that it plans to replace Jay Leno's new 10 00 p.m. variety show on NBC with a local newscast. The decision was made by owner Ed Ansin, who told the Boston Globe , "We feel we have a real opportunity with running the news at 10 p.m., ... We don't think the Leno show is going to be effective in primetime. It will be detrimental to our 11 o'clock. It will be very adverse to our finances." But John Eck, an NBC official who is technically on vacation, vowed to cancel the network's affiliation with WHDH, calling its decision to drop the Leno show "a flagrant violation of the terms of their contract with NBC," and adding, "We have a number of other strong options in the Boston market, including using our existing broadcast license to launch an NBC-owned and operated station."
