Sample and Hold
According to a study by the Council for Research Excellence and The Nielsen Company, broadcast radio accounts for more than half of all audio media exposure each day. The most time spent listening to broadcast radio is in the car. Broadcast radio was also widely used among users of other forms of audio media. For instance, 81.6 percent of those who used portable audio devices, such as an MP3 player or Ipod, also listened to broadcast radio. Likewise, 90 percent of satellite radio users also listened to broadcast radio for an average of 109 minutes per day.
