Based on market capitalization, Apple has official become the largest tech company in the world, passing Microsoft. Thanks in large part to ridiculously successful sales of the iPhone, iPod, and now the iPad as well as continually growing Mac sales, the company has slowly but steadily chipped a way at a market once entirely dominated by Windows-based products. Market cap, according to Wikipedia, is “a measurement of size of a business enterprise (corporation) equal to the share price times the number of shares outstanding of a public company.” During regular trading hours today, Apple’s shares (AAPL) dropped $1.11 to finish the day at $244.11, which sets its market cap somewhere around $222 billion. By comparison, Microsoft’s stock (MSFT) fell $1.06 to $25.01, for market cap of about $219 billion. Although this is mostly important to stock investors, specifically those who invest in those two companies, it is a huge first for Apple and is a title I’m sure they are hoping to hold on to for quite some time.

Remember those commercials that Microsoft spent an obscene amount of cash on that portrayed Jerry Seinfeld and Bill Gates as best buds shopping for shoes? No? That’s probably because they dropped the ads like a bad habit and moved on to greener pastures. Here’s a reminder:

Now you remember? Ok, lets continue. Rumor has it that Jerry Seinfeld is back to using Macs and the picture below, snapped during the filming of an episode of Curb Your Enthusiasm, seems to be proof positive.

Welcome back, Jerry!

Apparently, Microsoft’s Bing search engine was holding some sort of contest to come up with a jingle for the site. For some unknowable reason, the winner (of a $500 prize) is a video named “Bing Goes The Internet” by a guy named Jonathan Mann. You can watch it in a below, but I warn you: It will get in your head, you will hate it, and you will probably never want to watch it again. Don’t worry, though, Microsoft has no plans to use it in a national ad campaign.
