President Obama: The Inauguration
...as the BBC's coverage dubbed it; it's probably officially known as "The Inauguration of the 44th President of the United States of America", or somesuch.
The BBC had a slightly irritating tendency to natter over bits of the ceremony. Not the most important bits, granted, but not 'nothing' bits either.
[Check out BBC News' full online coverage of the inauguration here. The programme itself should be coming to iPlayer soon.]
