When did it happen?

Take a look at this news item:

 

Screen resolution 800 x 600 significantly decreased for exploring the internet according to OneStat.com

 

Amsterdam - July 25 - OneStat.com ( www.onestat.com ), the number one provider of real-time intelligence web analytics, today reported that more and more internet users choose for screen resolution 1024 x 768 which is the most popular screen resolution for exploring the internet.

 

The finding has important implications for web site designers because most web sites are designed for a screen resolution of 800 x 600 pixels.

 

The screen resolution 1024 x 768 has reached an all time high and has risen from 54.02 percent in June 2004 to 57.38 percent. Users with monitors set to the most common resolution 800 x 600 for web sites have an approximate 18.23 percent global usage share. A year ago this percentage was 24.66 percent.

Only one detail is missing from this page - the year. When did this happen? We can guess from the last paragraph that the article was published in 2005, but it does not say that.
