If I used the CNN logo on my website, would this be trademark infringement?

basically, I had a number of text adverts on the CNN website a while back. Since then, I've put up a CNN logo on my site to say my site was seen there. However, is this still trademark infringement? Also, might the logo be misinterpreted to mean an endorsement of my site? How can I stop that whilst getting the recognition my site deserves? Thanks in advance
