* At 11: 59AM on June 10, 2012 Time Warner Cable began broadcasting WBRE's programming in the Upstate NY region during a re-transmission dispute involving WPTZ, a station in Plattsburgh, New York owned by Hearst Television.

In 1998 after Argyle merged with Hearst Corporation's broadcasting unit ( creating Hearst-Argyle Television ), it swapped WNAC along with WDTN in Dayton, Ohio to Sunrise Television in exchange for WPTZ in Plattsburgh, New York, WNNE in Hartford, Vermont, and KSBW in Salinas, California.

The Guild's production of One Mad Night in 1940 was the first three-act play performed on television, when it was broadcast on WPTZ, in Philadelphia, Pennsylvania.

The substitution of WBRE in place of WPTZ, WESH and WXII lasted until July 19, 2012, when the deal was reached between Hearst and Time Warner.

Channel 4 nearly lost its NBC affiliation in 1955 when Westinghouse balked at NBC's initial offer to trade sister stations KYW radio and WPTZ television ( now KYW-TV ) in Philadelphia in exchange for the network's radio and television combination in Cleveland, Ohio.

KYW acquired a television counterpart when Westinghouse bought WPTZ ( channel 3 ) -- the nation's third commercial television station and NBC's second television affiliate -- in 1953.

Until early 2009, it was the only wireless website in the market when WPTZ added the service.

WFFF began operating as an independently-owned and controlled station around the same time Hearst took over WPTZ / WNNE when the LMA with WPTZ was terminated.

It was a subject of a blooper when Oprah Winfrey taped a promo for her show for WPTZ and started laughing after she spoke the station's community of license.

The substitution of WBRE in place of WPTZ lasted until July 19, 2012, when the deal was reached between Hearst and Time Warner.

WPTZ continued to air a locally-derived version of Weather Plus until August 31, 2009 when it was replaced with This TV.

WPTZ was one of six remaining stations owned by Hearst that has yet to make the upgrade to 16: 9 enhanced definition widescreen or full HD, until on April 26, 2011, when WPTZ started airing newscasts in widescreen.

" Swap Time " was one of them ; viewers could bring their unwanted items to the WPTZ studios to trade them live on the air with Kovacs.

Kovacs ' television programs included Three to Get Ready ( an early morning program seen on Philadelphia's WPTZ from 1950 through 1952 ), It's Time for Ernie ( 1951, his first network series ), Ernie in Kovacsland, ( a summer replacement show for Kukla, Fran and Ollie, 1951 ), The Ernie Kovacs Show ( 1952 – 56 on various networks ), a twice-a-week job filling in for Steve Allen as host of The Tonight Show on Mondays and Tuesdays ( 1956 – 57 ), and game shows Gamble on Love, One Minute Please, Time Will Tell ( all on DuMont ), and Take a Good Look ( 1959 – 61 ).

In February 2009 Hearst-Argyle announced that its stations ( except for KITV and its satellites in Hawaii, which had already completed their transition to digital, and WPTZ in Plattsburgh, New York and WNNE in Hartford, Vermont, which followed the other Champlain Valley in transitioning on February 17, 2009 ) would comply with the new DTV transition date of June 12, 2009.

As with most Canadian stations, the prime-time schedule is usually synchronized with the original American airings of the same programs because all major stations serving the Plattsburgh / Burlington area -- WPTZ, WVNY, WFFF-TV and WCAX -- are available on cable in Montreal.

Kovacs created the character for his program Three to Get Ready on WPTZ in Philadelphia ( the station that is now KYW-TV ).

WCBW closed down its operation on the old Channel 2 at the end of February 1946 ( the 60-66 mHz band had been re-allocated to WPTZ in Philadelphia ) in order to move to a new channel 2 at 54-60 MHz.

WPTZ is owned by Hearst Television, and has its studios in Plattsburgh and transmitter located on Mount Mansfield in Vermont.

The sale protected new Fox affiliate WFFF-TV which was initially operated by WPTZ under a local marketing agreement ( LMA ) and shared the analog transmitter on Terry Mountain.

David Letterman in another promo during his NBC tenure, riffed on the station's request for him to pronounce the " Z " in WPTZ as " zed " instead of " zee " for the station's Canadian audience.

WPTZ launched Weather Plus on a new second digital subchannel on November 15 after debuting a new digital signal from Mount Mansfield a day earlier.

This marked the network's first foray into the Plattsburgh and Burlington area along with St. Lawrence County in New York and eastern portions of the adjacent Watertown market where WPTZ has long served as the default NBC affiliate on cable.

On the American side, WPTZ can be seen in New York State on Charter channel 2 and in Vermont on Comcast channel 5.

In order to cover that state, WPTZ operates secondary facilities known as the Vermont Bureau on Roosevelt Highway ( U. S. 2 / U. S. 7 ) in Colchester.

During newscasts on WPTZ, WNNE is referred to as the Upper Valley Bureau and features a full-time reporter based in its White River Junction studios.

With the departure of Thom Hallock ( whose contract was not renewed by station ) on November 23, 2007, WPTZ was left with an all-woman weeknight anchor team.

In early 1952, Kovacs was also doing a late morning show for WPTZ called Kovacs On the Corner.

The first morning news program was Three To Get Ready, a local production broadcast by WPTZ from 1950 until 1952 in Philadelphia, Pennsylvania.

On July 9, 2012, WPTZ's parent company Hearst Television was involved in a dispute with Time Warner Cable, leading to WPTZ being pulled from Time Warner Cable and temporarily replaced with Nexstar Broadcasting Group station WBRE-TV of Wilkes-Barre, Pennsylvania ; Time Warner opted for such a distant signal like WBRE, as they do not have the rights to carry any NBC affiliate closest to them.

While both were cancelled, the morning program suffered the same fate as his WPTZ show-the air time being taken by the station's network in 1954.

Eddie Cantor is broadcast from NBC's Manhattan station WNBT to Philco's Philadelphia station WPTZ, via an automatic relay tower halfway between the two cities.

On May 25, 1944, pioneer television station WPTZ ( now KYW-TV ) in Philadelphia presented a special telecast featuring Eddie Cantor, which was also fed to the NBC television station in New York City, WNBT ( now WNBC ).

WPTZ, virtual channel 5, is an NBC-affiliated television station located in Plattsburgh, New York, USA.

However, WPTZ had dropped North Pole from its station IDs some years earlier, instead identifying as " Plattsburgh / Burlington.

He left WPTZ in 2005 to report at sister station WTAE-TV in Pittsburgh and made his debut back at this station in mid-December.

Westinghouse's first station purchase was with WPTZ in Philadelphia, in 1953.

In 1941 the station became the third commercially licensed TV operation in the United States as WPTZ.

After being rebuffed by Westinghouse on several occasions, NBC threatened to drop its affiliation from WPTZ and Westinghouse's other NBC television affiliate, WBZ-TV in Boston, unless Westinghouse agreed to the trade.

According to several sources, the coercion and extortion charges stemmed from NBC's threat to drop its programming from WPTZ unless Westinghouse agreed to the trade.

Showing up at NBC's Philadelphia affiliate, WPTZ ( now KYW-TV ), for an audition wearing a barrel and shorts got him his first television job.

It opted to keep the larger WLWT and trade WDTN, together with WNAC-TV in Providence, Rhode Island, to Sunrise Television for WPTZ in Plattsburgh, New York, WNNE in Hartford, Vermont, and KSBW in Salinas, California.

When Westinghouse balked, NBC threatened to pull its programming from WPTZ and Boston's WBZ-TV unless Westinghouse agreed to swap its Philadelphia stations for NBC's WTAM-AM-FM and WNBK in Cleveland.

In June 1955, Westinghouse agreed to trade KYW and WPTZ to NBC in exchange for the network's properties in Cleveland, WNBK television and WTAM-AM-FM.

The new owners changed the station's call letters to the present WPTZ ( for PlatTZburgh ); the WPTZ calls had recently been dropped by the channel 3 facility in Philadelphia following its controversial trade by Westinghouse Broadcasting to NBC earlier in that year.

Sunrise then decided to swap WPTZ / WNNE, along with Smith Broadcasting-owned KSBW in Salinas, California to what was then known as Hearst-Argyle Television in return for WNAC-TV in Providence, Rhode Island and WDTN in Dayton, Ohio.

In advance of the launch of NBC Weather Plus, the weather center was expanded to make room for new combined WPTZ / WNNE weather graphics and logos.

The Westinghouse Electric Corporation, owner of Philadelphia's NBC radio affiliate KYW ( 1060 AM ), purchased WPTZ in 1953 for a then-record price of $ 8. 5 million.

In June 1955 Westinghouse agreed to trade WPTZ and KYW radio to NBC in exchange for Cleveland's WNBK television and WTAM-AM-FM, and $ 3 million in cash compensation.

Hearst was forced to trade WNAC together with WDTN in Dayton, Ohio to Sunrise Television in return for WPTZ in Plattsburgh, New York, WNNE in Hartford, Vermont, and KSBW in Salinas, California because of the FCC rule forbidding common ownership of two stations with overlapping city-grade signals ( same rule that forced CBS to sell WPRI two years earlier ).
