The development of rock as a genre in Botswana has been a slow one. The music has however started to gain some momentum, partly due to the youth's exposure to mainstream media like MTV, Channel O and the internet. Metal Orizon, the country's first heavy metal band, was formed in the early 1990s. The native Batswana have since showed appreciation for this genre. Ever since the year 2000, a lot of bands have been formed. Most these have played locally and a few have toured southern Africa. Fans keep up to date with the music through word of mouth, tape trading and social networks, and there is a 50-minute show broadcast on national radio which plays metal music. The rock culture is now evidently recognised, with bands coming together to fight AIDS under a tour titled "Rock Against AIDS".
