The National Football League (NFL) is the undisputed leader in the professional American
football industry (college football games are played at different times so as not to compete
for the same viewers). Recent attempts to launch competing leagues (USFL, XFL, and AFL)
have been unsuccessful, but the NFL is compelled to spend an enormous amount of money
and effort innovating and marketing its entertainment services. This is an example of which
of the Five Forces?
1.

Bargaining power of suppliers.
Rivalry among existing firms.
Threat of new entrants.
Threat of substitutes.

21) A children’s sports league is currently keeping its records on paper and has asked you to
design a data model so they can track their information in a database. For each child, the
league has: first name, last name, age, address, whether a boy or a girl, and a note to
indicate asthma or other medical conditions. They tell you that first and last name is good
enough to identify a child. Each child has his or her own emergency contact, and for each
emergency contact the league has: name, phone number, and relationship to the child. The
league intends to use this database for many years, and over time each child will be on
multiple teams. Of course, each team will have several children on it, and the league tracks
the following about each team: sport, team name, coach’s name, number of wins, number
of losses, and number of ties. For each child-team assignment, the league tracks the jersey
number and position the child plays on that team.
Create the entity relationship diagram for an appropriate data model. Be sure to indicate the
identifier for each entity (if any) and the relationships between entities using the crow’s-feet
method.

22) The Internet has affected the video rental industry in profound ways. Prior to the
Internet, brick-and-mortar stores would buy VHS cassettes from studios and rent
them to consumers. Advances in information technology transitioned the industry
to DVDs, but this did not have a major impact… the stores simply started buying
new movies in DVD format. What really changed the industry was the creation of IT
linkages between the studios and the stores. Now a studio could see exactly when
a particular copy of a movie was rented; this allowed the store to hold many copies
of a movie and pay the studio a percentage whenever one of them is rented. It also
enabled three new distribution channels: video on demand, mail order (Netflix), and
unattended vending machine (Redbox).
Using Porter’s Five Forces, describe the changes to the “video rental” industry from the
introduction of the Internet and digital distribution. The rental companies’ suppliers are the
studios. The rental companies’ buyers are individual consumers. Netflix and Redbox are
part of this industry… they just use different distribution channels than most of their
competitors.

•
Supplier’s Bargaining Power:
• stronger: studio has information of sales at stores
• unchanged: competitiveness in film making industry has not changed
Buyer’s Bargaining Power:
• stronger, customers have more choices
• weaker, as quality of DVD has improved, it attracts more customers
Threat of Substitutes:
• stronger, video on demand, even piracy, is cheaper
Threat of New Entrants:
• stronger, lower upfront fixed cost as the store only pays when a DVD is rented,
allows a lower barrier of entry
Rivalry among Existing firms:
• stronger, number of stores increases, homogeneous product that is difficult to
allow product differentiate, may lead to price war and lower profit in general
GOOD LUCK !
