MTV began in the 1980s as a cable TV channel dedicated to music videos in the United States, and eventually expanded to over 170 countries worldwide primarily targeting youth aged 14-35. In its early international expansion, MTV struggled to gain popularity outside of the US until it adopted a localization strategy, developing localized content and hosts that spoke the local language to better understand each country's unique music scenes and culture. Over time, MTV was able to capture a significant share of the advertising market in most regions by adapting its programming to be more locally relevant while still maintaining some global content.
