Although it is unlikely that CBS is purposely linking to the files, they are most likely using an RSS feed aggregator that includes torrent trackers.
There is the chance however, that CBS has decided on purposely linking to the trackers. In April, CBS’s chief research officer David Poltrac spoke out about how YouTube and BitTorrent should be considered friends and not foes. He based his sentiments on a CBS poll that showed that people who download TV shows actually watch more TV.
Poltrack is also a believer in free TV over the internet, supported by ads. In his own words, “if [consumers] are going to steal it, give it to them anyway. But also make it easier to access and present it better than YouTube or BitTorrent or anywhere else.”
