Above the line (ATL)

Above the line (ATL), below the line (BTL), and through the line (TTL), in organizational business and marketing communications, are advertising techniques, or different strategies companies use to sell their products.
ATL communications use media that are broadcast and published to mass audiences. ATL is a type of advertising through media such as television, cinema, radio, print, and Out-of-home to promote brands or convey a specific offer. This type of communication is conventional in its nature and is considered impersonal to customers.
“Through the line” refers to an advertising strategy involving both above and below the line communications. This strategic approach allows brands to engage with a customer at multiple points (for example, the customer will see the television commercial, hear the radio advert and be handed a flyer on the street corner). This enables an integrated communications approach where consistent messaging across multiple media create a customer perception.
