Bono stopped by 'The Daily Show' (Weeknights, 11PM ET on Comedy Central) to talk about the (RED) campaign. It's a program helping to stop the spread of HIV and try to stop AIDS in its tracks, and they've made tremendous strides.

What (RED) does is make it easier than ever for people to get involved. Bono explained, "Sometimes people, you know, it's too complicated. They don't want to put on the marching boots. They just say how do I help?"

The answer is simple. Buy (RED) products -- which are available everywhere and include everything from shoes to iPad 2 Smart Covers to special edition Starbucks cards -- and a portion of those proceeds will go to help battle AIDS. Check out the Join(RED) website to learn more, and see some of the products available.
