For my new media technology work i will be researching digital television and digital radio:
Digital television refers to the sending and receiving of moving images and sound by means of discrete (digital) signals, in contrast to the analog signals used by analog TV
Digital Radio describes radio technologies which carry information as a digital signal.

List of possible research areas:
What is Digital Switchover?
What effect does the digital switchover have on the population?
What effect does it have on businesses?
How will viewing figures be affected?
Will digital television and digital radio have an effect on how companies make their mony?
Will it change the type of entertainment we watch and affect the times of the popular shows?
