YEAR 2006 The overview for 2006 includes printed media, television, outdoor advertising, radio, the Internet and cinema. Data for radio stations is based on 2005 estimates and on market feedback. GROSS VALUE OF PUBLISHED ADVERTISEMENTS The gross value of published ads was calculated from printed media, television, outdoor advertising, the Internet and cinema. When interpreting the results bear in mind that new media emerge and existing get cancelled in every year. The Mediana IBO marketing agency began measuring cinema advertising in February 2003. Including data from cinemas resulted in changes to the gross value of advertising. The agency began to monitor ads on the Internet in 2005, and ads in inserts in 2007. TV sales are not included in the gross value of advertising. Companies that offer cinema, the Internet and outdoor advertising themselves send data on ads they published. ESTIMATED NET VALUE OF ADVERTISING The estimated net value of advertising includes printed media, television, outdoor advertising, the Internet and cinema. The list of included media changes each year due to new media on the market. This must be taken into consideration when interpreting the estimated net value of published ads. The estimated net value is calculated by subtracting assessed discounts, (co)advertising package-deals and participation in awareness raising campaigns from the gross value of published ads.
