Editing CIOO-FM (section)

==History==
In 1976, Radio 920, Ltd., a division of [[CHUM Limited]], applied to the [[Canadian Radio-television and Telecommunications Commission]] for a new [[FM radio]] station broadcasting at 100,000 watts with a dial position of 100.1&nbsp;MHz. This would be the third FM radio station in Halifax after FM stations [[CBH-FM]] and [[CHFX-FM]]. Radio 920, Ltd. also owned [[CTV Television Network|CTV]] affiliate [[CJCH-DT|CJCH-TV]] and [[CJCH-FM|CJCH-AM]]. The CRTC subsequently approved the application.

On November 1, 1977, CIOO began broadcasting as an [[easy listening]] station using the branding ''C100''. As a new decade approached, CIOO changed its programming format to [[album rock]]. This gave listeners an opportunity to hear more than just the [[top 40]] hits from a particular artist, such as other songs not yet on AM radio. In 1983, [[CHUM Limited]] tested a simulcast project with new TV station [[Atlantic Satellite Network|ASN]] by airing ''Atlantic Canada's Choice'', counting down the week's best albums from 20 to 1 that was simulcast on both radio and TV and hosted by Geoff Banks. This lasted until spring 1985, where the station again reformatted its programming.

The spring of 1985 saw the station take on another programming angle, [[Top 40]] along with [[oldies]], such as [[The Beach Boys]] among others. This format was phased out not long after, when the station moved towards [[adult contemporary]]. The station utilized such slogans as "Lite Rock... Less Talk", "Great Light Rock Hits" and "...Even More Lite Rock Hits". CIOO moved to a [[Hot AC]] format in 1993. Like most hot AC stations in Canada, CIOO leaned rhythmic, though not as heavy as sister station [[CHUM-FM]]/[[Toronto]]. With sister station [[CJCH-FM]] adopting a [[Rhythmic contemporary|Rhythmic]]/[[Dance music|Dance]] Top 40 presentation by 2013, CIOO modified its playlist towards a conventional [[Adult Top 40]] direction. New sister stations since 2013 are [[Truro, Nova Scotia|Truro]]-based [[CKTY-FM]] and [[CKTO-FM]].

On December 21, 1984, CHUM Limited was denied a license to add an FM transmitter at 94.9&nbsp;MHz in [[Middleton, Nova Scotia|Middleton]] to rebroadcast the programming of CIOO.<ref>[https://crtc.gc.ca/eng/archive/1984/db84-1049.htm Decision CRTC 84-1049]</ref>

On December 27, 2020, as part of a mass format reorganization by Bell Media, CIOO rebranded as ''[[Move Radio|Move]] 100'', ending 43 years of the "C100" branding. While the station would run jockless for the first week of the format, on-air staff would return on January 4, 2021.<ref>[https://radioinsight.com/headlines/203466/bell-media-moves-ten-stations-to-new-branding/ Bell Media Moves Ten Stations to New Branding]</ref>

In 2022, CIOO flipped to [[adult contemporary]].
