WHTM-TV (channel 27) is a television station licensed to Harrisburg, Pennsylvania, United States, serving the Susquehanna Valley region as an affiliate of ABC.

WTPA was founded by the Newhouse family, whose media holdings eventually became Advance Publications, and was operated alongside Harrisburg's two major newspapers, The Patriot and The Evening News (since merged as The Patriot-News).

The Times Mirror Company acquired the Newhouse television stations (including WTPA) on March 28, 1980, and changed its call sign to the current WHTM-TV.

An ice storm that hit South Central Pennsylvania on December 15 and 16, 2007, knocked out the power to WHTM's transmitter site, which also affected the reception of the station on some cable and satellite providers.

[3][4] Feature reporter Chuck Rhodes served as a minor cast member in the 2000 film Lucky Numbers, which was based loosely on the 1980 Pennsylvania Lottery scandal and starred John Travolta as a cash lacking meteorologist, whose biggest competition in Harrisburg was Rhodes; the real-life incident occurred in Pittsburgh and involved fellow ABC affiliate WTAE-TV.

[20] On December 3, 2018, Nexstar announced it would acquire the assets of Chicago-based Tribune Media—which has owned Fox affiliate WPMT (channel 43) since 1996—for $6.4 billion in cash and debt.

Nexstar was precluded from acquiring WPMT directly or indirectly, as FCC regulations prohibit common ownership of two or more of the four highest-rated stations in the same media market.

(Furthermore, any attempt by Nexstar to assume the operations of WPMT through local marketing or shared services agreements would have been subject to regulatory hurdles that could have delayed completion of the FCC and Justice Department's review and approval process for the acquisition.)

Starting in 2012, WGAL began experiencing declines in news viewership, the largest occurring in May 2013; WHTM saw consistent growth, including significant gains during that same sweeps period.

The station increased its power to 28.1 kW and rotated its antenna 180 degrees to improve its signal in the main population area of the television market, including Dauphin, Lancaster, York and Lebanon counties.

The station previously had its antenna turned to the west to originally protect the analog signal of Philadelphia's WCAU during the digital transition in the 2000s and prior to 2009.

In addition, to improve its market coverage, WHTM's main channel (27.1) is simulcast in high definition as a subchannel on four low-power television stations.
