Brad Tuttle presents the marketing concept of targeting and
positioning in his online article: ‘In the Fast Food World, Is
Fish the New Chicken?’ (February 8,
2013). The article displays how McDonalds and other fast food
companies are altering their menu to position themselves to
religious and health-concerned
consumers and how this marketing campaign has broadened to
target segment members.
In the opening paragraph the author has identified the issue/s
under discussion and ensured they let the reader know which
article they were discussing.
Although they go hand in hand, the differences between the
marketing concepts of positioning and targeting are distinct.

12. Positioning is the “developing *of+
a brand image to appeal” (Sharp, 2013pg221) to particular
audiences. The concept of positioning can be categorized into
place, time and/or method.
McDonalds in the case of Tuttle’s article recognized an
opportunity to position itself to a wider range of buyers through
the use of fish-orientated menu
options. In this example, the franchise positioned the marketing
of this product through the function of time, specifically the
March/April period, “to
coincide with lent” (Tuttle, 2013pg1). Lent being the time
before Easter when Catholics traditionally steer away from
chicken, beef and pork (Tuttle,
2013:1), it seems only right from a business perspective that
McDonalds cater to the behavioural preferences of buyers
during this time.
Clearly in the 2
nd
paragraph the author has explained the marketing concepts and
related them to the article. They have used pertinent comments
from the
article to assist their arguments.
In addition to the concept of positioning through time, it was
noticed that fish, like chicken, was not only convenient for
typically Catholic people, but also

13. convenient from a cost perspective. Fish is an “affordable,
quick, and healthy snack” (Tuttle, 2013:1) meaning that sub-
groups other than said religious or
traditional audiences, could be introduced to the meal option.
For example those seeking healthier fast-food options,
specifically Mothers concerned about
healthier children’s meals (Tuttle, 2013:1) or time-poor people
who could also be attracted to the idea of on-the-go fish
throughout the entire year. This
idea more specifically relates to what is called segmentation-
based targeting.
In the 3
rd
paragraph the debate continues to demonstrate clear links
between theory & the McDonalds article.
Targeting is the “practice of creating differences in the
marketing mix to cater *for+ different segments” (Sharp,
2013pg221) Like McDonalds, it was
furthermore identified by Carl’s Jr. and Hardee’s that additional
sub-groups could be targeted for the fish trend. The idea of
utilizing Nina Agdal, in their
marketing campaign, was that “the healthy lass” would match
the “healthy” sandwich (Tuttle, 2013pg2). However the

14. sexualized characteristics of the
advert allowed for weight-conscious and body-concerned
audiences to become more interested in the product owing to the
swimsuit model. The
justification of this advert is that different sub-groups have
different want and needs and that a part of their market may not
be attracted to fish purely
because of lent. The advert was therefore tailored to offer its
menu to a greater range of target segments.
In the last paragraph the concept of targeting is defined &
referenced correctly from the course textbook. As this is only a
short assignment there is no
requirement for a conclusion.

New Google Maps app features street-by-
street navigation

New Google Maps app for Android phone, featuring turn-by-
turn navigation with live traffic
updates. Source: Supplied
THE first Google Maps overhaul since 2009 was due to arrive
on Android phones and
tablets late on Wednesday tonight, offering new features and an
advanced alternative to
in-car GPS devices and Apple's much-maligned rival
application.
The new Google Maps mobile app features built-in street-by-
street navigation for the first
time, as well as live traffic updates and guidance around traffic
jams.
A simpler look, 3D perspective shift, and restaurant reviews
also feature.
Google product communications associate Stephanie Shih said
the redesigned Maps app
would add live traffic updates for the first time, along with

16. street directions that had
previously been available in a separate app.
The new traffic updates would alert drivers as they travelled,
she said, proposing quicker
routes if a traffic jam or accident was reported.

id.apps.maps
"If you were taking a route to a friend's party and there was an
accident reported to our third-
party provider on the way, for example, it could reroute you
based on that accident," Ms Shih
said.
Google Maps product manager Nobuhiro Makida said the new
phone and tablet apps would
also feature a new single search bar "to show you the features
you need when you need
them", including car, public transport, walking and cycling
navigation.
It could also be used to search for a type of business rather than
an address, such as nearby
pizza restaurants.
While not comprehensive, more than 100 million businesses are

17. listed worldwide, with star
ratings provided by users and third-party providers, as well as
details and indoor panoramic,
interactive images taken by Google.
The update will be progressively rolled out to Android
smartphones and tablets, though only
those with Ice Cream Sandwich software (v4.0.3) or later will
be able to download the
update.
Mr Makida also said the location-sharing feature Google
Latitude that could pinpoint a user's
friends on maps, would be removed from the Maps with this
update, and moved to its
Google+ social network.
More than one billion people use Google Maps monthly, Ms
Shih said, making it the most
popular mapping app.
But the internet giant suffered a blow to its user base when
Apple removed Google Maps as
the default navigation app for the iPhone last year, replacing it
with its own mapping service.
Apple Maps has since been widely criticised, however, for
incorrect locations and directions,

18. missing streets, and warped satellite imagery that made some
buildings appear to melt.
Ms Shih said Google planned to launch the new Google Maps
app for Apple iPhone and iPad
in future, though no date had been set.
