Some advances in 20th-century puppetry have originated in the United States. Marionette puppetry was combined with television as early as the 1940s, with Howdy Doody of the United States being a notable marionette in this field. Bil Baird worked on revitalising marionette theatre and puppetry in the United States. He and his wife, Cora Eisenberg had their own marionette theatre in New York. Ventriloquist, Edgar Bergen also made a major contribution. In the 1960s Peter Schumann's Bread and Puppet Theater developed the political and artistic possibilities of puppet theatre in a distinctive, powerful and immediately recognizable way. At roughly the same time, Jim Henson was creating a type of soft, foam-rubber and cloth puppet which became known collectively as Muppets. Initially, through the children's television show "Sesame Street", and later in "The Muppet Show" and on film, these inspired many imitators and are today are recognised almost everywhere. Wayland Flowers also made a major contribution to adult puppetry with his satirical puppet, Madame.
