Outdoor advertising growth results from technological advances seen primarily on two fronts. First a rating measurement system for outdoor advertising, launched in 2004, is widely available and provides reach and frequency estimates. As a result, outdoor advertising is deemed much more effective, in terms of cost-per-thousand, than the other media. Secondly, improvements in digital print and high definition monitors have drastically increased the quality, variety and flexibility of outdoor advertising.
