In fact, North American consumers adopted e-commerce so much that despite growing fears about identity theft, they spent $172 billion shopping online in 2005, up from $38.8 billion in 2000.

By 2010, consumers are expected to spend $329 billion each year online, according to Forrester Research. What’s more, the percentage of U.S. households shopping online is expected to grow from 39 percent this year to 48 percent in 2010.
