Branded web series are the new big thing for marketers, with the typical series consisting of a half-dozen five-minute episodes costing an average of $100,000 to $1 million to create. (This isn’t so bad considering a typical 30-second spot can cost more than three times the price the most expensive web show). But are they working? Ad Age points out ten that are (based on the client renewing the series and the impressive number of eyeballs watching the shows). It’s an interesting list with some name-brand stars attached. Take a look.
