ga.js

If you’re still using the old Google Analytics code, you’re not alone

In late 2007, Google upgraded the tracking code script for Analytics. The new script, ga.js, offered a number of significant improvements over the old script, urchin.js. If that didn’t convince you, it also offered some assurance: Google would be maintaining ga.js going forward but urchin.js support would end at some point within 12-18 months.

Given how important web analytics are to online publishers, one might have expected websites to switch over to the new code pronto, especially major websites.
