Extending an advertising spot with a HbbTV presentation is a way to maximize the strike of your target audience on TV with a possibility to measure (“internet-like“) the viewers who used the HbbTV application and, primarily, to add an unlimited possibility for the viewer to get additional information about the broadcast spot. This suggests a comparison with the Internet world where an advertiser creates a special thematic microsite to supplement a current banner campaign. Same as on common www pages the technology enables measuring the activity of the viewer and therefore gives an accurate picture of the audience response to the campaign.
