E-cigarettes have become increasingly prominent since hitting the shelves of your local convenience store just 6 years ago. They may not be big business just yet, yielding $2.5 billion in total sales compared with the traditional tobacco industry's $80 billion in sales, but they are growing-fast. In fact, many industry observers have gone so far as to say that eventually sales of e-cigarettes could begin to eclipse sales of traditional cigarettes. Such a change would have major ramifications not only for consumers, but the shareholders of major tobacco companies like Altria (NYSE:MO) and Reynolds American (NYSE:RAI) . Tune into this week's consumer goods edition of Where the Money Is to find out how this major trend will affect the tobacco industry at large.
