TVARK is an online archival website of images, sound and video clips illustrating British television presentation history. Content includes idents, programme promotions, title sequences, public information films, commercials, daily start-ups and closedowns, break bumpers and station clocks. Each item has a short written analysis. The selection of clips represents the work of many broadcasting and production companies, principally the national and regional divisions of the BBC and ITV, plus Channel 4/S4C, Channel 5, various British Sky Broadcasting (formerly Sky Television and British Satellite Broadcasting) networks, and a few other digital, satellite and cable channels. Programme clips are grouped into genres such as quiz shows, fundraising events and imported shows. This website is dedicated to the founder's late mother, Valerie Hackett. History Television Ark was founded in the dial-up era on 8 November 1998, as a one-man hobby site. There were just a few pages containing a handful of low resolution clips that were easy to download, but were smaller to look at than an average postage stamp. Over the years, clips and images grew in size and quantity. The site expanded and was run entirely as a hobby by an eight-man team, with updates and additions made whenever time permitted. In December 2005, they absorbed the remains of SchoolsTV.com, a website dedicated to television programming for schools. During the summer of 2006, it was announced on their home page that they were having a summer break and would relaunch the site in the future. Unfortunately, higher resolution copies of previous clips were never made. The site relaunched on 25 December 2006 with very limited content, as well as few better quality clips put into a new download system in an effort to prevent hotlinking and preserve bandwidth. This proved very unpopular as clips took much longer to view, especially for those with slower internet connections. In addition, the relaunch saw the addition of a semi-transparent watermark (DOG) to new clips added to the site, to discourage "web snatching" of clips. Despite this, clips from TVARK have appeared on other sites, notably YouTube. In July 2009, TVARK announced the end of RealMedia used on the site, with videos now using Adobe Flash streaming in H.264/MPEG-4 AVC, and the service called TVARK Interactive will include user accounts commenting on video statistics. Since mid-2016, updates have ceased on the site. However, its social media pages (notably Facebook and Twitter) are being regularly updated
