ABC to expand hit show "Dancing With the Stars'
BEVERLY HILLS, Calif. - ABC's summer filler Dancing With the Stars was such a huge hit and generated so much viewer debate over the telephone voting system and the final outcome that the network is expanding the show to two nights when it returns early next year.

ABC Entertainment president Stephen McPherson in a news release Wednesday said the network is going to extend the next run to include more weeks of competition, and add a weekly 30-minute results show when judges' scores will be combined with the results of viewer votes.

Dancing With the Stars was the biggest summer ratings hit since Survivor in 2000. McPherson said the changes were a direct reaction to viewer frustration over the voting process.
