CNN has announced that its two-part Planet in Peril special, documenting environmental crises across the globe, will be made available at the iTunes Store an unknown period of time after the show's October 23rd and 24th airings. The video has been recorded in HD quality, and will be sold for $1.99 per episode. CNN has taken special effort to promote Planet in Peril to Apple customers; on Sunday the news network screened 40-minute excerpts at Apple Stores in Chicago, London, Los Angeles, New York City and San Francisco.

CNN will also distribute the series through Amazon, Netflix and its CNN Mobile Live cellphone service, as well as cable video-on-demand channels. Among the tools used for promotion so far have been audio and video podcasts, the former covering extra topics, the latter covering behind-the-scenes footage.
