The New Yorker, which is apparently a magazine and not a sandwich, has an article on the history of cell phone ringtones, the little bits of MIDI and MP3 that accounted for four billion dollars in revenue last year. While the history may not be enlightening—they started crappy, then got better—it serves as a decent round-up of the state-of-the-art in coworker frustration, as well. They neglect to mention the nascent trend among the cutting edge, where discordant sine waves are loaded onto different phones, forcing the evacuation of cerebrospinal fluid through the ears of every other person in your sales meeting.
Yes, this was the worst clip art I could find.
