Quotes by dates 
I arranged the quotes by date and (re)added the three periods 1980s/1990s/2000s because this concept is evolving over time from IT oriented to Business focussed. When more quotes will added, this will become more obvious.
For example in the 1980s the term EA is not being used untill the end of the 1980s. So to complete the picture here, I will probably have to search for and add quotes which are about the similar subject without the term beeing used. -- Marcel Douwe Dekker 09:15, 2 December 2009 (UTC)
