On Tuesday, Barack Obama will make history when he’s sworn in as the forty-fourth president of the United States of America. Let’s pause to reflect on how how we got here: Here are the president-elect and his forty-three predecessors (counting Grover Cleveland as two presidents, of course). Click on any or all of ‘em, and you’ll go to relevant sites around the Web. (I tried to be nonpartisan; many of them are the appropriate presidential libraries.)

And if you’re less interested in presidencies past and more interested in the one that’s about to start, check out my friend and former colleague Mark Sullivan’s guide to following the inauguration on the Web over at PCWorld.com.

With movies, it’s unquestionably 1939, the fabled year that saw the release of Gone With the Wind, The Wizard of Oz, Stagecoach, Wuthering Heights, Dark Victory, and Goodbye Mr. Chips. With baseball, there are multiple contenders, including 1924, 1949, and 1998…but I’m a Red Sox fan, so let’s just say it–it was 2004. Rock music? Maybe 1967, the year of The Beatles’ Sgt.

But what was the greatest year in technology history–the one that saw the highest number of significant products appear and/or other important events transpire? As far as I know, nobody has ever asked that question, let alone attempted to answer it. Will you join me in trying to figure it out?

In the coming days, Technologizer will recap significant moments, year by year and decade by decade, and give you the chance to vote on the years that made the biggest difference. For reasons of practicality, we’re beginning all this with 1970–we’re pretty sure that the greatest year, whatever it may be, happened in the past 39 years. (If you want to advocate for an earlier year, we’ll give you the chance to do so at some point via write-in votes; anyone know for sure what year the wheel was invented?) We’re also defining technology to cover personal technology relating to information and entertainment: PCs, Web stuff, TVs, MP3s, phones, and GPS, but not airplanes, cars, or clones. Eventually, we’ll winnow down the contenders and determine a winner.
