Television is a live medium and is constanty adapting to satisfy the viewers' needs. Recently, due to the digital revolution, it is facing ever more serious threats which relate primarily to the replacement of classic television with new, portable, and always connected devices. Additionally, viewers want more and more autonomy and freedom in choosing television content. When it comes to viewing habits, theorists emphasize an increasing share of using other devices to view television content, the growth of popularity of video-on-demand platforms and smart television, and increasing amount of watching time shifted content. Advertising also has to adapt to these viewing changes, as television is still one of the most effective media, especially for building reach. It mainly does so with new advertising formats and increasing importance of spot positions in advertising breaks. Television is still very important from the viewers' and advertisers' perspective in Slovenia. That is why I wanted to find out how Arianna, which is the most important software for television research on the Slovenian market, adapted to five key trends listed above. By analyzing the program's structure and the data available to the user I realized that Arianna responded entirely to two of the key trends, partially to another two, and that it did not respond to one of the five trends. According to this I can conclude that Arianna partially adapted to the key changes in television usage and advertising.
