Radio ? Sorry to say it wasn't effective. –
Now, keep in mind, we're a convention and not a haunted attraction.
However, I would imagine that the rules apply similarly.
After talking to dozens of guests about our advertising:
Our most popular (in no particular order)
PODCASTS (certain ones)
FLYERS (ones in the shape of a door hanger)
CERTAIN MAGAZINE ADS (some magazines work awesome, others didn't)
Our least popular (some of them not even being picked ONCE!! in the survey.)
RADIO (Our radio ads even included FLASH MOB advertising for free tickets!! NOT EFFECTIVE !!!)
FLYERS 8"x11" with coupons (Different type of flyers, distributed at other conventions and select HOT TOPIC stores)
PENNYSAVER NEWSPAPER ADS (you know, the local free newspaper that you pick up at restaurants.)
These newspaper ads were coupons
OTHER CERTAIN MAGAZINE ADS (some magazines work awesome, others didn't)
