There is a possibility that "Lost" will not premiere the sixth season as scheduled. The White House has added February 2 as the date when President Obama will deliver his first official State of Union address. The speech was supposed to air on January 19 and 26 but they have reportedly been switched to January 26 and February 2.
There is no official statement yet from the White House other than the date submission. They are allegedly buying time to complete the health-care reform package before the speech is done. In that case, Obama is expected to tell the public that they have reached a huge step toward a better nation.
"Lost", which is airing its final season, is slated to have a two-hour premiere on February 2 on ABC. Since the clash of schedule was announced, there has been a campaign on Twitter, #NoStateofUnionFeb2, which is against airing Obama's speech in place of "Lost".
The other networks have also anticipated/less-anticipated shows on the Tuesday slot. CBS has "NCIS: Naval Criminal Investigative Service", "NCIS: Los Angeles" and "The Good Wife", NBC has "The Biggest Loser", and FOX has "American Idol".
