"Between 2019 and 2021, the combined income of all the sectors studied increased by 44%. The sector with the most significant percentage growth is internet advertising, impacting other traditional media industries (newspapers, radio, and television) which have experienced a decrease in relative market share. Within the telecommunications sector, notable increases in income from ISPs, stable revenue for mobile telephony, and a decline in revenue from fixed telephony and the multichannel video distribution (MCVD) are observed. Overall, high levels of concentration exist in the media, telecommunications, and internet industries. The internet applications sector shows the highest concentration according to the CR4 indicator, followed by telecommunications, and then the media and cultural industries. When considering the HHI indicator, online news and the written press exhibit lower levels of concentration. Television demonstrates moderate yet important concentration. Compared to Argentina and Brazil, Chile has a higher number of broadcast TV channels competing for audience interest. Conversely, certain internet services showcase very high HHI values, hinting at near-monopoly situations. Over the three years under review, there is relative stability aside from declines in audiovisual streaming services. Netflix, initially facing challenges in Latin America, is now encountering heightened competition." (Executive summa[internal remarks]
