The power of the medium proposed is not in movement, but rather in changing information.
If bank interest rates go up or down, the ads can be changed immediately.
If a brand wanted to do a one-day price special, the ads can be updated.
If it’s a hot day, the ice cream and soft drink companies can post an ad to convince the consumer to buy their brand.
If it’s a wintery day, the hot drinks/tea brands can do the same.
It also lets advertisers communicate multiple product benefits of their brand, at once or at different times in the day.
The benefits of a digital, internet-connected billboard for you seem clear: we can add interactivity, we can update the
messaging in real-time, and we can reuse the ad on the internet and in other digital formats.
