Funny/sad/thought provoking/brilliant/informative/infographable public radio show This American Life (oh wait, I forgot to add "Peabody-Award-Winning!) is in less danger than a lot of public radio shows, because it's great and everyone rightfully loves it. But it's still available as a free podcast, and given its popularity, that hosting costs lots of money. So the show has two fundraisers per year by necessity.
As an experiment, in December 2009 the show tried out a new mobile giving method of donation. Mobile giving allows people to text a certain code to a certain number, and a certain amount of money will be charged onto their phone bill and donated to their cause of choice. It's been used highly effectively for causes like the Haiti earthquake, and the staff of This American Life saw no reason why it shouldn't be just as effective for a nonprofit like themselves.
The only problem: While the number of donations did double, from around 20,000 in June to 40,000 in December, the amount of money raised stayed about the same. That's because the stock donation mobile users gave was only $5—those same people might have donated far more online. The show's producers were happy with the results anyway (saying they liked that more people were donating, even if it was less per donation), but the show will raise the stock amount to $10 per text come the next fundraising drive.
It's a great system: I listen to lots of public radio, but it's always when I'm out and about and I usually forget that I'd wanted to donate by the time I'm in front of a computer and able to do so. But if I could just send a text (with the same device on which I'm listening to the radio, even), I'd be much more likely to donate.
