If you’re older than 21, you probably remember Super Bowl XXXIV in 2000, when no less than 14 internet companies had commercials during the game. Some people thought that was the peak of the Dot Com Era; instead, it was actually the end, or drastic demise, of the dot com era. By the end of that year, only a couple of the website that had commercial were still in existence, the others having gone bankrupt.

Since that time, there hasn’t been a lot of interest in most internet stocks. Sure, Google has jumped way up there, but most of the rest haven’t done much, and they’re almost seen as an afterthought.

Until now. Suddenly, internet stocks are on the rise again. What’s going on? Check this information out:

* Google’s revenue was up 27% in the third quarter;

* Amazon and Netflix both hit their highest stock price ever on Friday;

* Priceline stocks are now trading at their highest level, surging 140% in 2009;

* Blue Nile stocks are up 165% in 2009;

* Even Yahoo showed an increase of $180 million after all their problems, though their stock price hasn’t escalated as much as the other internet companies.

Internet companies are starting to flex a bit of muscle again. Powerhouse Facebook is suddenly worth $10 billion, and no one is sure what Twitter is estimated to be, since they refuse to disclose any financial information about their company.

More and more companies are starting to understand the power of the internet, and are starting to get into the game. Last year, one blogger was able to sell his site for around $15 million; that’s a fantastic amount for a blog that wasn’t even ranked all that high, a finance and banking blog that, counter to public beliefs, was not the motivation for creating this blog (although, if anyone is reading this who has big dollars, more than the $300 I was offered two weeks ago, I’d be willing to entertain any 6-figure offers). It’s a new world, and it seems that maybe not everyone has learned the lessons from almost 10 years ago just yet.

Still, it’s probably a good time to start looking into some of these stocks. Some analysts are saying they believe some of these companies might be overvalued, so be cautious.
