Optimizely is A/B testing. It's not strictly analytics (in that it's not a Google Analytics replacement), but it re-implements some of that functionality for audience targeting. Krux is an ad tracking service. jsmd.js appears to be the homebrew analytics system of one of the media partners. The actual web analytics being run on CNN is Adobe Analytics, which is actually fairly compact. The real problem is that every ad also includes its own analytics framework. Each of them often includes multiple frameworks, each of which tracks something different. E.g. one for demographic targeting, one for tracking across multiple ad networks, one to see if the user scrolled far enough to see the ad, and one to see if the ad loaded before the user closed the page or navigated away. It's a goddamn mess.
