*Puts Business Head On*

Adverts on TV - These are probably the most effective, however are expensive if you want to advertise during a prime time show, are C4 going to want to spend lots of money to advertise a show which is unlikely to get high rating anyway?

Radio - can be effective, but not everyone listens to radio

Billboards - Again, can be effective however they're very expensive and are targeting the same people, i.e. people who travel past the same billboard to get to work, the billboard is only seen by these people.

Adverts on Websites - Can seem very tacky

Adverts during Movie Trailers - Very expensive, probably more so than TV ad's due to the fact that the audience have to watch it and are unable to flick over like they can on TV.
