In 2006 i have invented a predecessor of responsive design and published about it on Alistapart. It’s called Switchy McLayout and offers a solution how to deal with content on various screen sizes.
In 2013 i have written an article about the enterprise scope of responsive- and adaptive design. It deals with aspects outside the conventional layout boundary. The dutch version has been published on Frankwatching.com and the english translation has been added to my frontend architecture blog.
