BT Vision is continuing to bring new channels and content to its UK television subscribers.
The pay-TV vendor has signed a contract with Viacom International Media Networks to bring a number of popular entertainment channels to its platform.
MTV, Comedy Central and Nickelodeon have all launched on BT Vision this month, increasing the range of options for viewers.
Marc Watson, BT’s Chief Executive of TV, said the firm is "really excited" about these channels coming to BT Vision.
"MTV is the pioneer in creating innovative programming for young people, with the best in music, celebrity news and reality TV," he noted.
"Comedy Central is cutting edge comedy overflowing with provocative, original programming and Nickelodeon is the number one brand in the world for kids."
The new channels join BT Vision’s growing portfolio - which already includes Universal Channel, Syfy, E!, Discovery Channel, Animal Planet, Real Time, British Eurosport 1 and 2, FX, National Geographic, National Geographic WILD and UKTV’s Gold, Watch and Alibi.
Meanwhile, BT Sport has signed a deal with the Women’s Tennis Association (WTA) to show up to 800 hours per year of live action from the ladies' tour.
The TV provider will show live matches from 21 WTA tournaments across the globe, including the season-ending showpiece TEB BNP Paribas WTA Championships.
The announcement coincides with an upturn in fortunes for British women’s tennis, with two British players ranked in the WTA Top-50 for the first time since July 1987.
Both Laura Robson and Heather Watson will be hoping to make an impression at the four Grand Slam events in 2013 - with Wimbledon a key target for the two rising stars.
The BT Sport deal is for four years and includes the five elite WTA tournaments – Indian Wells, Miami, Madrid, Beijing and Istanbul.
During the 2013 season, the rights will be held jointly with Eurosport, but from 2014 will be exclusively owned by BT Sport.
Simon Green, Head of BT Sport, said there is a "genuine opportunity" to develop the exposure for women’s sport with the broadcaster's new channels.
"We are focusing on several more women’s sports and we hope to be able to announce more rights soon," he stated.
BT Sport has already secured live top flight football and rugby union rights from the 2013-14 season.
