That JavaScript looks related to serving or tracking ads. The code makes reference to DART (part of DoubleClick) and Ad Ops, and it's on the same part of the page as all of their other analytics tools (Google Analytics, SiteCatalyst, etc). Comcast is probably not in direct control of the code, and may be in the position that they can't get rid of it without adversely impacting their ad revenue stream.
