MSNBC's coverage of next Tuesday's presidential inauguration will be shown in 27 U.S. theaters, the cable news channel said Monday. The video will be distributed in standard definition by Screenvision, the company responsible for the advertisements presented prior to the screening of features in many U.S. theaters -- and, more recently, the live presentation of baseball and basketball sports events. The inaugural screenings will be presented free in 21 markets but will require those interested in attending to sign up online for tickets being distributed on MSNBC's website.
