Los Angeles (AP) The strike by Hollywood writers is on.
Writers and studios broke off talks late Sunday after 11 hours of negotiations.
The talks between the Writers Guild of America and the Alliance of Motion Picture and Television Producers were called by a federal mediator. The producers said a deal couldn't be reached.
The writers want more money from the sale of DVDs and a share of revenue generated by the sale of TV shows and films over the Internet. The studios say the demands are unreasonable and will hamper attempts to experiment with new media.
Picketing starts in the morning in New York and Los Angeles.
The walkout will impact late-night talk shows first, then daytime talk shows and soap operas. Studios have stockpiled movie scripts and prime-time TV has completed shows in hand to last until early next year.
