Amplitude Modulation. or...
Ante meridien and post meridien, meridien meaning midday. So AM is before midday and PM is post (after) midday.

If it is with regards to time, it tells where is the position of the sun.
AM = ante meridian (before meridian line)
PM = post meridian (after meridian line)
Noon = directly on top of the meridian line
Meridian = an imaginary great circle on the surface of the earth passing through the north and south poles at right angles to the equator; "all points on the same meridian have the same longitude"
Example:
11am = the sun is before the meridian line
01pm = the sun is shining after the meridian line
12 noon = the sun is at it's highest point and is shining directly on the meridian line.

AM means amplitude modulation. It relies on changes in signal strength (height of a wave) whereas FM (frequency modulation) relies in changes in signal frequency (distance between waves.)

AM stands for "ante meridiem" from Latain.
