Riverdale came back from hiatus strong. Roswell had a strong premiere. That leaves us tied for 3rd in the 18-49 demographic and 4th when total viewers are added. We will have to see if Riverdale continues to be strong and how Roswell holds in the upcoming weeks. We did not place in the weekly top 10 for Nielsen Social Ratings.
