What do details in the first part of the excerpt tell about the nature of breaking news stories in the 1914 press as compared to today? How does the second part differ from the first in terms of its tone and information?

The rise of advertising in the 1920s. i am good with seeing how advertisements shape the roaring twenties and how it developed a new way of life through modern days. but i am not sure what the details of advertising in the 1920s were. if possible can you send me links (preferrably credential links) to sources that maybe show like the first company to start advertising through the radio, how advertising benefits (statistics graphs), etc.
