Took a look at the dev console, there are 2 tracking scripts, segment and CNN specific one. Those take up the majority of bandwidth. There's also a separate CSS style sheet. The main DOM and the stylesheet are <10% of the total bytes transferred. The favicon is the same byte size as the entire DOM.
Don't think there is necessarily a consideration of byte cost, given the size of the tracking scripts. A few lines to make this manageable on wide monitors aren't prohibitive for those users.
