Starbucks & Paramount Pictures: First Advertisers on Yahoo Mobile

I'm always browsing the web on my Blackberry and I really like to use Yahoo! Mobile, as pointed out in my posts here.

I am deeply interested to see who will be the first movers to advertise on Mobile screens and for a while I had only seen Yahoo! promoting it's own products, like Yahoo! Go.  However lately, in New York City, where I spend most of my time, I've seen fresh new graphic banners from corporate advertisers.  The first two that I have seen are:

For me, I just find it intriguing to see who are the first movers into mobile advertising.
