Final answer:
Technological advancements can either help small firms expand their reach and compete in broader markets or lead to the dominance of large companies with superior resource capabilities.
Step-by-step explanation:
Technological advancements are expected to significantly impact field sales efforts in various ways. One effect is that these advancements may enable small firms to expand their reach beyond their local geographic area and find customers statewide, nationally, or even internationally. However, new technology might also contribute to the creation of 'winner-take-all' markets where one or a few large companies dominate a significant portion of total sales. Furthermore, information and communications technologies could make it easier to manage numerous operations, thus encouraging larger firms. In essence, technological change is driving a shift in market structures that could lead to either the proliferation of nimble small competitors or the concentration of market power among a few large entities.
