In response to both listener and member feedback, Iowa Public Radio is changing its weekend programming schedule, beginning Saturday. Iowa-produced shows "Backtracks" and "Classical Music With Barney Sherman" will be given extra air time, while national programs, including "The Moth" and "The TED Radio Hour," will be given more prominent time slots to increase listener reach.  IPR will also add several new shows and expand local programming.
