Instore TV- Right message on the right palace

In the US there are more than 130,000 locations with over 500,000 digital screens.

Broadcasters said these digital networks offer advertisers access to consumers at the point of purchase, measurability of advertising impact and the ability to target niche markets.

Out-of-home digital advertising is among the fastest-growing segments of the marketing pie, accounting for $1.5 billion in ad spending now and growing steadily — 25% per year, according to Stephen Diorio, a partner in research firm Profitable Channels, who added, "This is a segment that is verging on legitimacy."

ESPN has more than 4.3 million out-of-home viewers per day, and CNN is second, clocking 3.85 million, according to a Total TV Audience Monitor (T-TAM) study.
