I have some decent "Watch [TV Show]" sites and i can't find any decent affiliate for this niche. I found some on clickbank, but they are not providing any promotional material.
The obvious stuff ... I have a few sites for TV shows and do reasonable off of promoting DVDs and official merchandise through Amazon, and collectibles/memorabilia via eBay and occasionally props stores like Premiere. None of these are huge moneymakers, but there's a wide variety, the product lines are self-updating and it tends to be pretty steady year-round. Frank
