We relive January 20, 2009 in Chicago, and reporter Ben Calhoun tells us how he is and his Chicago traveling companions are feeling. We keep hearing about the digital television conversion but there’s a new technology on the horizon called mobile television. Chicago Tribune technology reporter Eric Benderoff and Eight Forty-Eight media contributor Wally Podrazik explain the concept and how it might change our lives.

There’s still time to contribute to our time capsule of January 20, 2009. Send your pictures, vidoes and comments to our blog.
