National Public Radio's Weekend Edition Sunday reported that New York City Democratic councilman David Yassky had called for a ban on obnoxious ring tones. The councilman claimed that objectionable ring tones were costing the economy upwards of $1.2 billion and were the cause of numerous fights induced by "ring-tone rage." As of April 1, 2008, NPR reported, cell phone users would be restricted to four city-approved ring tones.
