"A World Denied - web accessibility the movie" says that although there are clear benefits from widening the audience for an organisation's website by making sure it is accessible to all, some 80% to 90% of all websites are not currently designed to be so.
The movie says that designing an accessible website need not be expensive or difficult, but that organisations that are not taking any steps in this direction are increasingly likely to fall foul of the Disability Discrimination Act and face court action, fines and reputation damage.
Available now, "A World Denied - web accessibility the movie" has been produced in association with AbilityNet, the charity that helps people with disabilities make use of computers and the internet.
The DVD's messages are aimed at senior managers, as the producers believe poor corporate commitment to website accessibility is due to low awareness of the issue among decision-makers and budget-holders.
Included in the DVD are some demonstrations of how an accessible website functions, and some short case studies showing how organisations such as Legal & General have benefited from making their website accessible.
"Around 8,000,000 people in the UK are thought to suffer some form of disability causing difficulties in using a standard screen, keyboard and mouse set-up," said Martin Greenwood of Socitm Insight.
The 12-minute DVD is available for free to subscribers of Socitm Insight and costs £50 for others.
