Two links to Glenn Fleishman in one day. Someone stop me before I Glenn again.
This time it’s on his own blog, extrapolating some numbers from recent social-media surveys:
Twitter’s growth has slowed, especially for active users. Podcasting has by no means reached its top, and it’s likely to be driven higher by a critical mass of adoption and shows like Serial. The number of podcast listeners could start to approach Edison’s figures for online radio listeners: about 47% of the 12+ population in America, or about 124 million people.
For people who love listening to and making podcasts, 39 million is a very nice potential audience, but striving towards 124 million sounds even better.
