Advertising sure has changed quite a bit over the years. For larger
companies, the days of nonstop corny (but memorable) jingles have pretty
much gone the way of the dodo, although you'll still hear a few from
time to time. Print, radio, and television advertising has had to adapt
to our culture, and observing these trends helps you to put a finger on
the pulse of what the United States and other countries all over the
world are currently into.
