<P> The network is available in HD on most of its full - power affiliates, while availability of high definition content on subchannel - only or cable - exclusive affiliates varies by market; in some of these cases, the over-the - air signal is available only in standard definition (a 16: 9 widescreen feed transmitted in 480i SD is presented on some over-the - air affiliates to meet minimum requirements for presentation), with the station offering an exclusive high definition feed to cable and satellite providers . Some affiliates transmit CW programming in 720p HD due to technical considerations if the network is carried on a digital subchannel of a station affiliated with another major network or if a primary feed CW affiliate carries more than one subchannel . Since June 2012, The CW Plus feed is also transmitted in HD, and the network has asked those affiliates to carry it in high definition wherever possible . </P> <P> With ABC beginning to use 16: 9 framing for all of their graphics on September 1, 2016, The CW, along with corporate parent CBS are currently the last two major networks that continues to use 4: 3 framing for all graphics (outside of CBS Sports). </P> <P> CW Seed (originally called CWD or the CW Digital Studio) is a production arm that provides original content created exclusively for digital platforms focused in the areas of animation, game shows, comedy and digital personalities . Included in the service is interactivity, feedback from viewers, and social engagement . Previously existing as a section on The CW's main website, CW Seed was spun - off to a separate website (cwseed.com) in 2014 . Original web series produced by CW Seed includes Stupid Hype, I Ship It, How to Be a Vampire, JoJoHead, Prom Queen, Husbands, and the Arrowverse series Vixen, Freedom Fighters: The Ray, and Constantine: City of Demons . In addition, CW Seed hosts archive programming including shows such as Constantine, Birds of Prey, Hellcats, Forever, Everwood, Dynasty, Pushing Daisies, Everybody Hates Chris, and Max Headroom . </P>
