TEENS were the fastest growing age-group among Cambodia’s television viewers in the last six months, according to market research company Indochina Research Ltd (IRL). Figures from IRL’s bi-annual survey show the Kingdom’s youth-dedicated network MYTV has 11 percent of the market, up from 7 percent in the survey released in January. The driver was an increase in 15- to 19-year old viewers, rising to 32 percent from 20 percent. CTN, meanwhile, saw its market share fall to 55 percent from 62 percent. “This decrease is mainly due to the increase of MYTV,” IRL said Monday.
