Every day our life is full of images, videos, music and news. In this age of visual and aural hyperstimulation（视听的高度刺激），the medium of radio is making a marked comeback.

“We're at the dawn of a golden age of audio," said US-based podcaster Alex Blumberg in an article in The Sydney Morning Herald.  In the last month alone, 15 percent of US adults listened to a radio podcast. These data, released by Edison Research, reveal the successful evolution of traditional radio broadcasts to the present day's digital podcast format（播客形式）.  The term "podcast," was coined in 2004, but the trend only started gaining mainstream popularity in recent years.  Since the leap in consumer demand for smart phones and tablets, podcast subscription rates have only accelerated.

You can tune in during those extra minutes of the day when you're walking to the shops, waiting in a queue or riding the subway.  Similar to television shows, podcasts are generally free to download on computer or iPod and most offer new content every week.

Donna Jackson, 22, Sydney University media graduate, listens to podcasts two or three times a week, via-iTunes.¨ I listen while I'm hanging out in the house doing something else.

It makes completing a boring task a lot more enjoyable... And it's an easy way of keeping in touch with what's going on in the rest of the world," she said.  “I mainly listen to BBC podcasts, but recently I've also been tuning into This American Life and Serial.”

Unlike television and music, the audio format has the ability to create a deep impression on readers. Blumberg says this comes down to the podcast's ability "to create emotional connection." Sydney University undergraduate Hazel Proust, major in social work and arts, agrees. "When you're tuned in, it feels as if the podcaster is talking directly to you. It's comforting," said Proust.

It seems the age-old tradition of verbal（口头的）storytelling is very much alive and well.
