Oops!  Ticketmaster is apologizing.

It accidentally sold a big batch of tickets to President Obama’s inauguration Sunday night, even thought they weren’t supposed to go on sale until Monday morning.

Ticketmaster  was testing it’s software Sunday night and sent out an e-mail inviting people to buy tickets to the Inauguration and the Ball.  Some people did respond.  Ticketmaster says it will honor those purchased tickets.

The Inauguration and Ball are not expected to be the “hot tickets” they were four years ago.  Many who attended then, are taking a pass this time.  Festivities have been scaled down to reflect the numbers.

Washington, DC officials expect between 600 and 800 thousand people for the swearing-in ceremony on January 21st.  In 2009, two million people attended the historic swearing in of the country’s first african american president.
