 Some international broadcasters have become available via Digital Audio Broadcasting (DAB) in Europe in the 1990s, and in a similar limited way in the Americas via in-band FM (IBOC) DAB systems in the US in the 2000s.This is a popular method to reach listeners in cars that would otherwise not be accessible during that part of the day.However, in terms of the global international broadcasting audience the DAB listener base is very small—one can assume that it is less than 2% of the listener base globally.
