(Telecompaper) Time Warner told investors that it plans to test reducing the number of ads shown on some of its Turner cable channels, starting with those targeting young viewers, such as TruTV, reports Variety. With youth channels, the plan is to decrease the volume of advertising to 10-11 minutes per hour, compared to 18-19 minutes at present. Instead of referring to an around 43 percent drop in advertising minutes, Time Warner described the move in its analyst call that it planned to increase the amount of programming per hour by around 21 percent.
