Trends and competition

I read a post by Ed Brill today on testdriving Google Trends. The competitive spirit in me was triggered by an attempt to compare the trend (popularity) between Lotus Notes and Microsoft Outlook ?

The overall trend line is downward, but that doesn’t worry me much — the same is true for the competition. Speaking of competition, several readers noted the comparative trends for Lotus Notes vs. Microsoft Outlook — Almost identical (blue = Notes, red = Outlook) …

So I thought what would be other good queries to compare trends ?

IBM, Microsoft :


Lotus Notes, SharePoint :


Sametime, LCS :


There must be dozens more either way, but these are a good conformation of my perception; especially on the RTC front (Sametime vs LCS) as of the middle of 2005 is quite clear …
