Former Alliance Atlantis execs have begun showing up at a Michael MacMillan-era GlassBOX Television.

Jennifer Mason joins the cross-platform broadcaster as marketing and communications director after executive stints at Shaw Media and then Alliance Atlantis Communications.

Mason most recently was senior manager of marketing strategy for Shaw Media’s HGTV, History Television, Showcase, TVTropolis, National Geographic, BBC Canada channels, and helped launch the Global Reality Channel.

Before that, Mason worked on international marketing strategies for Alliance Atlantis.

She will now turn her attention to driving audiences to GlassBOX Television broadcast assets like Bite TV, AUX TV and the newly acquired Travel and Escape Channel.

Mason’s appointment follows former Alliance Atlantis topper Michael MacMillan taking the helm at GlassBOX Television as a diversification by the former pure-play broadcaster into an increasingly digital business.
