«According to the respondents in the study, AM/FM radio listening comprised only 62 percent of the hours they spent listening to the radio in the week prior to being surveyed. The total share of listening to AM and FM radio increases to 70 percent when listening to AM/FM streaming is included. Online streaming represents 16 percent of all reported time spent with radio, split evenly between AM/FM streaming and Internet-only radio. Satellite radio and the music channels offered through cable and satellite TV systems each account for an 11 percent piece of the pie. Among this sample of online consumers, listening to podcasts represent only 1 percent of total time spent with radio.Hanson added, "What this study highlights is that while Arbitron data may show that AM/FM listening is declining slightly each year, the bigger picture is this: Listening to radio in all of its forms is almost certainly growing significantly."» fonte FMQB, Online Consumers Flock To New Forms Of Radio, 11/04/08
