At a gala coinciding with the United Nations' International Day of Persons with Disabilities on December 3, 2008, the NBRS announced that The Accessible Channel would officially launch in January 2009. The organization also announced that TAC would carry closed captioning on all of its programming: while the CRTC's standard conditions of licence for digital services at the time only mandated that 90% of programming be captioned, the NBRS felt that committing to caption all of its programming was consistent with its goal to make TAC an "inclusive" service. The Accessible Channel subsequently launched on January 29, 2009.

To reflect its expansion beyond VoicePrint, the National Broadcast Reading Service was renamed Accessible Media Inc. (AMI) in 2010. On January 30, 2012, as part of an effort to unify AMI's services under one brand, TAC was renamed AMI-tv. VoicePrint followed suit on March 5, 2012, becoming AMI-audio.

On December 4, 2012, AMI-tv launched a high definition feed on the MTS Ultimate TV service in Manitoba.

In January 2013, when the CRTC opened a new round of applications for must-carry channels, AMI submitted an application for a French-language sister channel of AMI-tv known as AMI-tv Français, which would have a similar format to its English-language counterpart. AMI justified the need for the channel by noting that the three provinces which host the majority of Canada's francophone population—New Brunswick, Ontario, and Quebec—had above-average levels of vision loss and other vision-related conditions. On August 8, 2013, the CRTC approved the application; the commission recognized that given the impact of AMI-tv's English service, a French service would have an equivalent impact on Canada's francophone community.

The service launched on December 16, 2014, as AMI-télé.

When AMI-tv launched, it was owned by a consortium made up of various other Canadian specialty services and producers; Showcase acting as manager partner in 50% (owned by Canwest), Accessible Media at 20%, and MuchMusic at 10%. On October 27, 2010, Shaw Communication acquired Canwest's 50% stake in AMI-tv. In 2011, MuchMusic sold 10% of its stake of AMI-TV to each of Shaw Media and Accessible Media, leading the two companies to each own 50% in AMI-tv.

On January 13, 2016, Accessible Media announced that it would acquire Shaw Media's 50% ownership interest in AMI-tv. The purchase was in relation to Corus Entertainment's pending acquisition of Shaw Media. The acquisition had been approved by the CRTC on March 23, 2016 to allow the sale of certain Shaw Media properties so that the purchase could clear regulatory barriers. On December 20, 2016, the CRTC approved Accessible Media's full ownership of AMI-tv and it was purchased by Accessible Media on January 1, 2017.

AMI-tv carries a general entertainment lineup of programming including sitcoms, television dramas, films, talk shows, and documentaries. Although AMI-tv is primarily aimed at adults, formerly a limited amount of programming broadcast during morning hours was aimed at children, including such programs as Little Bear and Franklin. The majority of programming on AMI-tv are Canadian productions supplied in conjunction with other major Canadian broadcasters such as the CBC and Bell Media; a smaller portion of programming is also sourced from foreign broadcasters and studios, but in any case, no more than 33% of its programming can be supplied by a single broadcaster, and at least 50% of its programming must contain audio descriptions produced by companies other than AMI. Until the launch of the dedicated channel AMI-télé, it also aired four hours a week of French-language programming in the same format.

AMI-tv also produces and airs original programming, primarily dealing with accessibility- and disability-related topics. Examples have included its 2011 documentary A Whole New Light, which focused on Canada's contributions to the research of vision loss, Milestones of Champions: The Journeys of Canada's Paralympians, focusing on the stories of notable Canadian athletes in the Paralympic Games, the cooking show Four Senses, and Employable Me. In these programs, audio description is integrated into the programs' main dialogue and narration.

AMI-tv has collaborated with other Canadian broadcasters to simulcast events on the network with open described video. In conjunction with CBC Television, the network provided audio descriptions and simulcasts of coverage of events such as the wedding of Prince William and Catherine Middleton, the 2011 federal election, the 2011 Gemini Awards, Canada Day festivities in Ottawa in 2012, and the 32nd Genie Awards. In conjunction with coverage of the games carried by CTV and Rogers properties, AMI-tv also offered coverage of the 2012 Summer Paralympics, including simulcasts of daily highlight shows with described video, and a daily program featuring interviews with athletes. The latter was hosted by AMI reporters Carrie Anton (who was a member of Canada's gold medal-winning goalball team at the 2000 Summer Paralympics) and Gary Steeves, both of whom are blind. AMI-tv's involvement in the Paralympics continued for the 2014 Winter Paralympics in Sochi, this time in conjunction with CBC Sports and the Canadian Paralympic Committee.

In September 2012, AMI-tv partnered with Sportsnet to broadcast three Toronto Blue Jays Major League Baseball games with described video provided by Sportsnet 590 correspondent Sam Cosentino, which included additional commentary such as explanations of on-screen graphics. Blue Jays president Paul Beeston praised AMI's involvement, stating that "to our knowledge, we are the first sports organization to have our games provided through this revolutionary approach to accommodating the needs of the blind and low-vision community." AMI-tv Blue Jays coverage was expanded for the 2013 season, with Cosentino joined by veteran sportscaster Jim Van Horne.
