Archival footage is commonly used in television news but can be subtly manipulated to direct viewers' focus. News programs also conduct interviews with correspondents around the world to report on current events. Editing techniques like L-cuts and title cards are used to transition between shots and identify people or organizations in an efficient manner. Each news channel has distinctive opening music to set tone and differentiate their brand. Channel idents through color coding and graphics in the opening also serve to distinguish one broadcaster from another. Anchors are frequently shown seated behind desks to convey authority though they may have limited direct information. Wide shots of the newsroom aim to psychologically connect viewers to global headlines.
