Kellogg's is a manufacture of cookie and cracker products.
 Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers)
 Mass production of sewing machines and agricultural machinery such as reapers occurred in the mid to late 19th century
