While watching Glee the other night, I noticed some marketing within the show. This show is overall incorporates a lot of marketing for popular contemporary music, covering songs throughout the series. However, I noticed something else. In one of the scenes when main character Finn was singing in his rooms, there were band posters strategically placed in the screenshot. Such artists are: Dashboard Confessional, Thrice, A Cursive Memory, and Kings of Leon.
Product placement in TV shows, films, etc. are also an effective marketing tool. Viewers of the show will see these posters and want to check them out to further connect with the character, Finn. (If Finn likes these artists, maybe his fans will too.) This is a great way to target new markets for these artists. Millions watch Glee, so it increases the exposure for these artists.
