[edit] Introduction
Low-power FM (LPFM) radio is a form of lower-power radio broadcasting used by non-commercial, community radio stations in the United States. It was created in 2000 as an answer to concerns about the centralization of radio stations into the hands of large corporations like Clear Channel. It's original intent was to license several thousand non profit entities (schools, churches, community groups, NPO's, fire, police, etc.). It was enacted, but was not implemented as originally intended due to pressure from the National Association of Broadcasters (NAB) and National Public Radio (NPR). Objections of interference with other stations were raised and a highly effective campaign in Congress was launched causing a 'rule' requiring no other staions be within 3 adjecent channels from a potential LPFM station. This rule effectively blocked out several thousand potential stations. In 2004, an independent study was released (created for the Federal Communications Commission (FCC)) that stated the 3rd adjacent channel rule was unfounded and should be stuck down. As of late 2005, the FCC has taken no additional action and only a few hundred LPFM stations have been licensed. No additional windows for application have been opened or announced.
