Editing Attack ad (section)

===Non-political usage===
While attack ads have primarily been relegated for political usage, there have been some instances of private businesses running them. In 2013, [[Highmark]], a healthcare company associated with the [[Blue Cross Blue Shield Association]], and the [[University of Pittsburgh Medical Center]] (UPMC) were unable to reach an agreement on whether Highmark's insurance would be accepted at UPMC. Highmark also entered into negotiations to acquire the struggling [[West Penn Allegheny Health System]]; Highmark and UPMC then started airing attack ads at each other. Both parties' ads accused the other of pushing patients with their respective [[health insurance]] plans to hospitals operated by their respective health insurance provider, as well as attacking each other's [[nonprofit]] status.<ref>{{cite web|url=http://pittsburgh.cbslocal.com/2013/08/01/upmc-and-highmark-engage-in-tv-ad-war/|title=UPMC and Highmark Engage in TV Ad Wars|date=August 1, 2013|publisher=CBS Pittsburgh}}</ref><ref>{{cite web|url=http://triblive.com/news/allegheny/4481931-74/upmc-highmark-health#axzz2bXiuA6El|author=Pucko, Timothy|author2=Conti, David|title=UPMC sues Highmark over advertising campaign|date=August 5, 2013|publisher=TribeLive News}}</ref><ref>{{cite news|url=http://www.post-gazette.com/stories/local/neighborhoods-city/upmc-pittsburgh-stake-positions-for-court-fight-on-nonprofit-status-680393/|author=Hamill, Sean D.|newspaper=Pittsburgh Post-Gazette|title=UPMC, Pittsburgh stake positions for court fight on nonprofit status|date=March 22, 2013|publisher= PG Publishing Co., Inc.}}</ref> At the same year, [[T-Mobile US|T-Mobile]], [[AT&T]], [[Sprint Corporation|Sprint]] and [[Verizon]] began airing attack ads against each other.<ref>{{cite web|url=https://www.businessinsider.com/att-made-this-t-mobile-attack-ad-2013-3|title=AT&T Made This T-Mobile Attack Ad|date=March 4, 2013|publisher=Business Insider}}</ref><ref>{{cite web|url=https://www.cnet.com/tech/mobile/t-mobile-fires-back-at-at-t-in-attack-ads/|title=T-Mobile fires back at AT&T in attack ads|date=March 6, 2013|publisher=CNET}}</ref><ref>{{cite news|url=https://www.tmonews.com/2013/07/t-mobiles-new-print-attack-ad-hits-att-verizon-again-and-again/|title=Home > T-Mobile's New Print Attack Ad Hits AT&T, Verizon Again, And Again T-Mobile's New Print Attack Ad Hits AT&T, Verizon Again, And Again|date=July 24, 2013|publisher=TmoNews}}</ref>
