Over the last several years, Google and Apple have entered the market and taken nearly all of it.

A new chart released by comScore gives a longer term look at what has happened in the smartphone industry. Six years has proven to be an eternity in this sector.

We can see that Microsoft, RIM, and Palm had owned the market prior to the entry of the iPhone from Apple and a slew of phones running Google’s Android operating system. Microsoft and Palm have lost all but everything, and RIM’s Blackberries are still in there, but are dwindling away and have become largely irrelevant.

Also note that these numbers are 3 month averages, meaning that the market share of the growing platforms, likely iOS and Android, is understated.
