i'm

Just realize this i'm™ campaign by Microsoft.

i’m is a new initiative from Windows Live Messenger™. Every time you start a conversation using i’m, Microsoft shares a portion of the program's advertising revenue with some of the world's most effective organizations dedicated to social causes. We've set no cap on the amount we'll donate to each organization. The sky's the limit.

So any time you have an i’m™ conversation using Windows Live Messenger, you help address the issues you feel most passionate about, including poverty, child protection, disease, and environmental degradation. It's simple. All you have to do is join and start an instant messaging conversation. We'll handle the donation. [source]
