In the web design industry, there have been a number of changes over the past few decades that have changed the way we design and program our sites. At one stage, Flash was a great way to play a video type message on your site that was relatively easy to embed. There were a number of problems with this especially when Apply produced the Iphone which did not support Flash, meaning it simply wouldn’t play on these devices. Also Google could not read the content within the Flash file so trying to optimise a site was hard work. Also from a user’s point of view, often it would make the site loading time longer and also sometimes mean they have to upgrade their flash player before they could continue with the site.
Now, designers and programmers are tending to use quirky techniques that allow users to interact with the screen often in a number of ways whist not limiting the people who can access it or how long it takes to access it, often this information is written in such a way that it can be read by the search engines too.
