Following the economic reforms in the 1990s, satellite television channels from around the world—BBC, CNN, CNBC, and other private television channels gained a foothold in the country. There are no regulations to control the ownership of satellite dish antennas and also for operating cable television systems in India, which in turn has helped for an impressive growth in the viewership. The growth in the number of satellite channels was triggered by corporate business houses such as Star TV group and Zee TV. Initially restricted to music and entertainment channels, viewership grew, giving rise to several channels in regional languages, especially Hindi. The main news channels available were CNN and BBC World. In the late 1990s, many current affairs and news channels sprouted, becoming immensely popular because of the alternative viewpoint they offered compared to Doordarshan. Some of the notable ones are Aaj Tak (run by the India Today group) and STAR News, CNN-IBN, Times Now, initially run by the NDTV group and their lead anchor, Prannoy Roy (NDTV now has its own channels, NDTV 24x7, NDTV Profit and NDTV India). Over the years, Doordarshan services also have grown from a single national channel to six national and eleven regional channels. Nonetheless, it has lost the leadership in market, though it underwent many phases of modernisation in order to contain tough competition from private channels.
