Through the 1800s, the form of the corporation took shape in an elaborate dance of wills. Entrepreneurs, torn between building legacies and extracting cash, led the dance; state legislators, torn between attracting corporations and limiting their power, followed.

New types of technological webs bound the country: railroads, steamships, electric power, telegraph and telephone lines. The newly invented rotary press enabled printers to put out 100,000 copies of a magazine; this, in turn, allowed national advertising to sprout, which made it profitable for consumer product giants to build brands.
