The 1988 strike lasted 22 weeks and TV ratings dropped about 9%, cutting the industry's revenue by an estimated $500 million. This time around, the rise of reality TV shows, 24-hour cable news networks and other forms of nonfiction programming has left professional writers with less clout. That said, some effects of the work stoppage will become quickly apparent on TV, especially on popular late-night comedy shows that are immediately going to reruns without their writing staffs on hand to poke fun at current events. Viacom's ( VIA ) Comedy Central network will begin reruns on Monday with its hit late-night shows, The Daily Show with Jon Stewart and The Colbert Report. At General Electric's ( GE ) broadcast network, NBC, The Tonight Show With Jay Leno is expected to be affected, as will be Jimmy Kimmel Live at Disney's ( DIS ) ABC and The Late Show With Dave Letterman at CBS ( CBS ).
