MSNBC's Sunday morning business/finance show, Your Business has become the first MSNBC program to tape from their new home at 30 Rock. An MSNBC insider tells TVNewser Your Business was recorded in studio 3K while "utilizing control room 3A which will be the main control room" for MSNBC.

Other insiders tell me show team rehearsals have been going on for several weeks, but it's still too soon to commit to a date for full show production to originate from 30 Rock. MSNBC will be moving from their Secaucus NJ headquarters to the 3rd and 4th floors of 30 Rockefeller Center, home of NBC News.
