20,000 calls per year. In the early days of Washington Journal, callers were not screened by ideology. This was changed at the recommendation of University of Maryland professor John Splaine, hired by C-SPAN to ensure the network's objectivity, who noticed that C-SPAN received a disproportionate number of calls from conservative viewers. Washington Journal producers now set up separate phone lines by party affiliation (Democrats, Republicans and Independents) and take alternate calls from each line. In some cases, a dedicated call-in line is made available for the international audience (outside the U.S. and Canada), or for a particular group of callers. For example, a program about college tuition may have a line for students and recent graduates. In the fall of 2006, Washington Journal recorded two shows in New Orleans and set up a call-in line for locals to tell their stories from Hurricane Katrina and its aftermath. Production The show is hosted from C-SPAN's Washington, D.C., studio overlooking the Capitol Building and is hosted by a revolving set of hosts. In November 2009, C-SPAN named veteran television news producer Michele Remillard as executive producer of Washington Journal. The Washington Journal theme music is the third movement of Concerto for Trumpet, no. 2 by Johann Melchior Molter (1696—1765), played at various points during each broadcast. The theme is used as introductory music, as an interlude during transitions, and is played again as the program concludes. Video simulcast of the C-SPAN Radio studio has been shown during transitions at the top of an hour, with the radio host reading the day's news headlines. The program airs 365 days a year. Washington Journal uses no delay, so obscene or other objectionable language will be occasionally heard, though offending callers are normally cut off promptly. Callers are asked to wait 30 days between phoning in, though this rule is pointed out to be violated by the program's regular viewers occasionally. Notable guests and events For several days following the September 11 attacks, Washington Journal began at 6 a.m. instead of 7 a.m. Following Hurricane Katrina, Washington Journal frequently featured discussions on the issue of New Orleans' recovery. On August 21 and 22, 2006, a remote broadcast was set up in the city to interview key players, including U.S. senators David Vitter and Mary Landrieu, and local homeowners. Among C-SPAN's primarily anonymous callers, recording artist and entertainer Cher made waves by calling into the show
