We'd stop short of calling it inevitable, but we aren't shocked one bit to hear that on-demand porn has landed on VUDU's set-top-box. Adult Video Network (AVN) has developed a channel for VUDU which enables users to rent and purchase SD or HD films just like any other less explicit title. As expected, users would be asked to first "verify their age" and clear parental controls before anything on the channel could be viewed. Interested in pricing details? Try $6.99 / $19.99 for SD rentals / purchases and $8.99 / $29.99 for HD rentals / purchases.
