Rome
The ornate Latin style was the primary form of oration through the mid-20th century. After World War II and the increased use of film and television, the Latin oration style began to fall out of favor. This cultural change likely had to do with the rise of the scientific method and the emphasis on a "plain" style of speaking and writing. Even today's formal oratory is much less ornate than in the Classical Era.
