Forum:Dates

I noticed that on different pages, the range of dates of browser releases vary. For example, on the Explorer page, we have 1995-2000, 2001-2006, and 2007-2011. Wheras, on the Firefox page, we have 2004-2006, 2007-2009, and 2010-2011. I was wondering if these are arranged so that certain versions are in one section, and others in another, or if it doesn't really matter and we can regulate them so that they are all the same. Thanks!
