ABC's Lostwill become just that after another season or two -- lost from the TV schedule, ABC Entertainment President Steve McPherson told the winter TV writers press tour Sunday in Pasadena. He said that ABC executives are currently in discussions with Lost's producers about ways to end the series. Damon Lindelof, one of the executive producers of the series, said that the show's creators had always planned to devise no more than 100 episodes. Thus far, 53 episodes have aired. Lindelof noted that other popular dramas were abandoned by audiences after producers began making questionable creative decisions to invigorate them. He specifically mentioned The X-FILES and Alias in that context. McPherson also said that the network will not break up the series as it did in 2006 when it aired six episodes and then put it on hiatus for three months. (It returns for 16 more episodes next month.) Next time around -- which could begin in the fall or the spring of 2008 -- Lost will run for 22 consecutive weeks. And in yet another announcement, McPherson said that it will delay the season launch of Dancing With The Stars until March 19, when it will air on Monday nights in order to avoid head-to-head competition with Fox's similar talent contest, American Idol.
