TO Channel in Australia. MacArthur is the subject of a song written in tribute to Call for Help 2.0. While working as a host on Call for Help, MacArthur joined the series Gadgets and Gizmos as a co-host, working with Marc Saltzman and Andy Walker until the show ended production in 2005. From August 2004 to September 2006, MacArthur was host of the G4techTV Canada program, Torrent, which is still in production. She also hosted Gadgets and Gizmos for the Canadian channel. On 28 August 2006, MacArthur announced on her blog that she was leaving her position at G4techTV and would no longer appear on Call For Help, Torrent, or Gadgets and Gizmos. In mid-September, she joined Citytv, CP24 in Toronto with the title "New Media Specialist", to report on "new media and interactive trends" for CityNews International. She first appeared on the station's nightly newscast, CityNews at Six, commenting in another reporter's story on 9/11 conspiracy theories propagated through the Internet. Segments since have ranged from former sex trade workers blogging the Robert Pickton trial, to a Toronto Transit Commission/Google Maps mashup. In January 2007, she launched a weekly program on CP24, which became quite popular as a vodcast. Originally titled "Inside Popnology", the CHUM Television-produced program quickly became Webnation. She resigned in October to go for freelance projects, feeling she was being asked to target too old an audience, and wanted to pursue two projects in the United States. They convinced her to stick around for two more months, after Rogers Communications promised her show would be weekly on the Citytv network and on G4techTV Canada, reformatted, as of January 2008 as Webnation V2. (CTV's parent company; CTVglobemedia bought out CHUM Limited in June 2007, with the exception of the Citytv network, which was sold to Rogers.) She was informed on 4 January 2008 that the budget was not there for the program. Just before the announcement, the program was named the "Top New Podcast Award for 2007" by iTunes. Citytv began airing The Lab with Leo Laporte around this time. CP24 has since made some reorganization to the anchors/reporters as a result of the change in ownership of CP24's former parent company; CHUM Limited. For a time, after David Onley was named Lieutenant Governor of Ontario, MacArthur hosted Home Page; Jee-Yun Lee replaced her when MacArthur resigned. MacArthur's Webnation replaced HomePage on the CP24 schedule 14 October
