agile “anything” began with the Agile Software Development. the basic idea here is to split whole software development project in smaller pieces (iterations) and instead of releasing software only in the end of the whole project they perform small releases in the end of every iteration. that allows you to get a working software in the end of every iteration, decide what should be done next, improve communication and planning.
from the resources on the web i tried to figure out how agile applies to the marketing function. some companies applied the Agile Software Development idea and even tried to apply the same software for process management. some companies declared that agile marketing is a name for the marketing in the online media (it was interesting to take a look at the source of the site 
).
i understand agile marketing as something which applies the same agile software development rules to the marketing world making possible to get usable results faster, apply changes easier, and communicate better. that means instead of huge complicated campaigns you have main idea which you can implement step by step getting fully functioning result in the end of every step. it’s easier and much cheaper to modify which is very valuable aspect in the rapidly changing marketing environment.
