Most international business radio is part of regular business radio, and usually talks about the "deal of the day." That type of content is like milk... it has an expiration date. For example, 2 weeks after the largest Asian or European merger happens, no one cares.
What have business executives been reading lately? It runs the gamut, truly. Some read only work-related periodicals and books. Others work in time for reading only nonfictions. Others read fiction voraciously as a way of relaxing and getting away from the grind for a short time each day.
