Go to your Profile. Click on the About section. Scroll down to the Quotations/Contact Info part and click on See More link to expand it. Scroll down to the TV shows section. Hover over each show and you'll see a Liked menu appear. Hover over that Liked menu and then select Unlike. You can also edit the privacy to keep the shows, but just not display them on your profile. You can also use the settings next in the arrow next to any of the show's posts to select to Hide them if you want to keep the show but just not see the updates.
