Editing Jack FM (section)

===Since 2006: North American format changes, international expansion===
Following the format's mid-2000s growth throughout North America, Jack FM continued to expand into smaller markets across the continent. However, in many cities the novelty wore off, and in the late 2000s a number of Jack stations modified their playlists drastically or flipped to other formats outright.

In May 2006, the playlist of [[CKIS-FM|CJAQ-FM]] in [[Toronto]] evolved into a [[mainstream rock]] format. The 1980s [[Top 40 (radio format)|top-40]] acts such as [[Madonna (entertainer)|Madonna]], [[Duran Duran]], [[Kim Wilde]], [[Cyndi Lauper]], and [[Falco (musician)|Falco]] were dropped in favor of an all-rock playlist, and the station's slogan changed to "Toronto's Best Rock Variety". However, In June 2009, the station flipped back to Contemporary Hits.  It returned to its former "Kiss" branding as well as adopted its current call letters.<ref>[http://www.925jackfm.com/ 92.5 JackFM] {{webarchive |url=https://web.archive.org/web/20050410044828/http://www.925jackfm.com/ |date=April 10, 2005 }}</ref> Similarly, Rawlco-owned CKCK-FM (the only non-Rogers operated Jack FM station) in [[Regina, Saskatchewan]], adopted a [[classic rock]] direction in September, changing its slogan from the traditional "Playing What We Want" to "The Greatest Rock Of All Time" and adding announcers to its afternoon [[drive time]] show. In 2010, the tagline was changed again to "Regina's Greatest Hits".

In October 2006, the UK's first Jack FM format station won a broadcast licence for the [[Oxford]] area.<ref>{{cite web |url=http://www.ofcom.org.uk/media/news/2006/10/nr_20061012 |title=Ofcom awards new FM commercial radio licence for Oxford and South Oxfordshire &#124; Ofcom |access-date=October 13, 2006 |url-status=dead |archive-url=https://web.archive.org/web/20070930041556/http://www.ofcom.org.uk/media/news/2006/10/nr_20061012 |archive-date=September 30, 2007 }}</ref> 106 Jack FM Oxford started broadcasting at 1:06&nbsp;p.m. [[British Summer Time|BST]] on October 18, 2007.{{Citation needed|date=June 2008}} On December 2, 2009, Bristol radio station Original FM changed to Jack FM after requesting a format change with OFCOM.<ref>{{cite web|url=http://radiotoday.co.uk/news.php?extend.5428 |title=Radio Today with RCS: Original replaced by JACK fm |access-date=December 9, 2009 |url-status=dead |archive-url=https://web.archive.org/web/20091204202439/http://radiotoday.co.uk/news.php?extend.5428 |archive-date=December 4, 2009 }}</ref> Two further Jack FM stations were planned on DAB digital radio from 2008 for Northamptonshire and Northeast Wales and West Cheshire{{Citation needed|date=June 2008}} but by August 2009 were a year late with no indication of an [[Estimated time of arrival|ETA]]. In addition the Oxfordshire Jack was to have been relayed to a wider area.
''RadioToday'' reported [[The Coast (radio station)|The Coast]] was to flip to become JACK FM on July 4, 2011.<ref>{{cite web |url=http://radiotoday.co.uk/2011/06/feature-is-jack-the-future |title=Feature: Is JACK fm the future of radio? |date=June 8, 2011 }}</ref>

In January 2007, [[KJJZ|KAJR]] in [[California]]'s [[Coachella Valley]] launched as a "Jack FM" affiliate in a region unable to receive the [[KCBS-FM]] signal from Los Angeles, {{convert|100| mi|km}} to the west.{{Citation needed|date=January 2009}} Jack did not last long.  By February 1, 2010, that station became [[soft adult contemporary]]-formatted KJJZ.

On October 22, 2007, [[WBMX (FM)|WJMK]] in Chicago announced that radio personality [[Steve Dahl]] would be morning drive personality as of November 5, the first personality on the station since it went to the Jack format. In March 2011, WJMK dropped the Jack format in favor of [[classic hits]] as "K-Hits", featuring 1960s to 1980s music. Eddie & Jobo (Ed Volkman and Joe Bohannon, former morning hosts at co-owned [[WBBM-FM]]) took over the morning show.

On June 29, 2012, it was announced that [[KLO-FM|KJQN]] in Salt Lake City would drop the "Jack FM" format on July 16, 2012, and begin to simulcast the talk radio format of [[KMES|KLO]].<ref>[http://www.radio-info.com/news/salt-lake-city-standalone-klo-1430-buys-kjqn-fm-1031]{{dead link|date=March 2017}}</ref>

On August 2, 2013, [[KFBG (FM)|KFMB-FM]], the Jack FM station in San Diego, began restricting access to its online stream to listeners within the city of San Diego proper.<ref name="RI 2013-08-08 KFMB-FM">{{cite news |url=https://radioinsight.com/headlines/84544/local-radio-behind-a-paywall/ |last=Venta |first=Lance |title=Local Radio Behind A Paywall |website=RadioInsight |publisher=RadioBB Networks |date=August 8, 2013 |access-date=April 22, 2020 }}</ref> This move by program director Mike O'Reilly drew the ire of fans who live outside the city limits, including the large [[Economy of San Diego#Defense and military|U.S. military community]] stationed locally and overseas. O'Reilly explained his rationale, citing a new [[Arbitron]] policy on how online listening is measured:

{{Quote
|text=Our radio industry is continually adapting to changing metrics, which are sometimes out of our control within our competitive landscape. I understand your frustration and I can assure you this decision to restrict our streaming efforts to San Diego was based on multiple factors including the licensing issues outlined on our website. In addition, radio stations that do not 100% simulcast their signals online are essentially competing with themselves. Technically they are considered two separate radio stations in the way they are rated. By restricting our signal to San Diego only, our online stream and our air signal at 100.7FM will be considered one unified station.
|author=Mike O'Reilly, KFMB-FM program director
}}

KFMB-FM achieved this effect by restricting the signal based on the IP address of the device on which a listener streamed the station. However, fans within the city of San Diego were prevented from hearing the station as well. In addition, the station charged for access to its local morning radio show on podcast in September 2013.<ref name="RI 2013-08-08 KFMB-FM" /> On November 17, 2015, KFMB-FM dropped its regular Jack FM programming and began [[Stunting (broadcasting)|stunting]] with all-Christmas music as "Jack Frost"; The station launched a [[mainstream rock]] format on January 4, 2016.<ref name="RI 2016-01-04 KFMB-FM">{{cite news |url=https://radioinsight.com/blog/headlines/95651/wheel-of-formats-kills-off-jack-fm-san-diego/ |last=Venta |first=Lance |title=Wheel of Formats Kills Off Jack-FM San Diego |website=RadioInsight |publisher=RadioBB Networks |date=January 4, 2016 |access-date=October 28, 2019 }}</ref>

On February 28, 2014, [[CFLT-FM]] in [[Halifax, Nova Scotia]], flipped formats to Jack FM becoming the latest Rogers radio station to adopt the Jack branding. Meanwhile, in February 2015, another Rogers station, [[CHTT-FM]] in [[Victoria, British Columbia]], dropped the Jack FM format and flipped to [[contemporary hit radio]] (CHR) as "Kiss 103.1". That station, however, returned to Jack FM programming on August 15, 2019.

On December 26, 2017, at midnight, [[KSAJ-FM]] in [[Topeka, Kansas]], flipped formats from oldies to Jack FM.

The Jack FM format is distributed via satellite in the United States and internationally. Within the US, distributed originally by [[Citadel Media|ABC Radio]] and later acquired by Dial Global (now [[Westwood One]]). In September 2019, Skyview Networks took over the US distribution rights from Westwood One.<ref>{{cite news |url=https://radioinsight.com/headlines/180665/after-losing-jack-westwood-one-launches-two-new-variety-hits-networks/ |last=Venta |first=Lance |title=After Losing Jack, Westwood One Launches Two New Variety Hits Networks |website=RadioInsight |publisher=RadioBB Networks |date=September 23, 2019 }}</ref> US military radio station [[American Forces Network#Radio|Armed Forces Network, Afghanistan]] broadcasts Jack FM, having adopted the format on August 1, 2011, as a way to expand the playlist and reduce operational personnel.
