NBC and Lorne Michaels have a novel plan to launch the next version of Late Night with new host Jimmy Fallon: online. The show will start online five to six months before debuting in its 12:35am slot on NBC. The idea is to give Fallon his sea legs. The idea grew out of Michaels’ experience launching the same show with Conan O’Brien. The online show will give him a chance to experiment with different kinds of comedy, and hopefully build a young audience.
