"These statistics indicate that TV studios should consider increasing their
marketing efforts on Facebook to take advantage of the organic interest in Liking Pages of TV shows," it writes. "Through Pages, they can strengthen fan loyalty, increase viewership, and sell
merchandise."
In particular, Facebook pages for shows such as "Family Guy" (30.2 million Likes), "South Park" (26.7 million), "Two and a Half Men" (18.8 million) and "Glee" (13.7 million) have converted their brands into huge followings without relying on advertising, Inside Facebook notes, adding that Liking a TV show has become a common practice -- not one reserved for just a show's biggest fans.
