Aggregated local and national advertising revenues grew in April by one percent, atoning in part for a 2% decline the previous month.

The latest US data, released by the Radio Advertising Bureau in New York, indicates the medium blossomed year-on-year by 3% in combined revenues during the four months to April 30.

This apparent good news, however, should be viewed against a trend of a slowing in growth over the past several months.
