There are countless opportunities for enhancing traditional TV through interactivity. The list of scenarios in this chapter is by no means complete.

All the scenarios presented in this chapter were implemented to some degree, either as demos, prototype, experimental deployments, or full scale deployments. Some of these scenarios have proven to be economical successes. It appears that for specific (possibly local) markets a successful specific variation emerges through creative thinking, detailed tweaking, persistence, and some degree of luck.
