A generation ago, consumers were at the mercy of advertisers who spoon-fed them marketing messages across a few media channels: print, billboards, television, radio. These advertisers created markets, defining and reinforcing consumer stereotypes. In the 1950s, advertising was primarily a one-way conversation with a captive audience. TV advertising grew and matured into a viable marketing medium. Experts were the style makers.
Those who follow after the Close Followers are known as the Late Entrants. While being a Late Entrant can seem very daunting, there are some perks to being a latecomer. For example, Late Entrants have the ability to learn from those who are already in the market or have previously entered. Late Followers have the advantage of learning from their early competitors and improving the benefits or reducing the total costs. This allows them to create a strategy that could essentially mean gaining market share and most importantly, staying in the market. In addition to this, markets evolve, leading to consumers wanting improvements and advancements on products. Late Followers have the advantage of catching the shifts in customer needs and wants towards the products. When bearing in mind customer preference, customer value has a significant influence. Customer value means taking into account the investment of customers as well as the brand or product. It is created through the “perceptions of benefits” and the “total cost of ownership”. On the other hand, if the needs and wants of consumers have only slightly altered, Late Followers could have a cost advantage over early entrants due to the use of product imitation. However, if a business is switching markets, this could take the cost advantage away due to the expense of changing markets for the business. Late Entry into a market does not necessarily mean there is a disadvantage when it comes to market share, it depends on how the marketing mix is adopted and the performance of the business. If the marketing mix is not used correctly – despite the entrant time – the business will gain little to no advantages, potentially missing out on a significant opportunity.
A strategic business unit (SBU) is a subsidiary within a firm, which participates within a given market/industry. The SBU would embrace the corporate strategy, and attune it to its own particular industry. For instance, an SBU may partake in the sports goods industry. It thus would ascertain how it would attain additional sales of sports goods, in order to satisfy the overall business strategy.
The product aspects of marketing deal with the specifications of the actual goods or services, and how it relates to the end-user's needs and wants. The product element consists of product design, new product innovation, branding, packaging, labeling. The scope of a product generally includes supporting elements such as warranties, guarantees, and support. Branding, a key aspect of the product management, refers to the various methods of communicating a brand identity for the product, brand, or company. 
Video advertising - This type of advertising in terms of digital/online means are advertisements that play on online videos e.g. YouTube videos. This type of marketing has seen an increase in popularity over time. Online Video Advertising usually consists of three types: Pre-Roll advertisements which play before the video is watched, Mid-Roll advertisements which play during the video, or Post-Roll advertisements which play after the video is watched. Post-roll advertisements were shown to have better brand recognition in relation to the other types, where-as "ad-context congruity/incongruity plays an important role in reinforcing ad memorability". Due to selective attention from viewers, there is the likelihood that the message may not be received. The main advantage of video advertising is that it disrupts the viewing experience of the video and therefore there is a difficulty in attempting to avoid them. How a consumer interacts with online video advertising can come down to three stages: Pre attention, attention, and behavioural decision. These online advertisements give the brand/business options and choices. These consist of length, position, adjacent video content which all directly affect the effectiveness of the produced advertisement time, therefore manipulating these variables will yield different results. Length of the advertisement has shown to affect memorability where-as longer duration resulted in increased brand recognition. This type of advertising, due to its nature of interruption of the viewer, it is likely that the consumer may feel as if their experience is being interrupted or invaded, creating negative perception of the brand. These advertisements are also available to be shared by the viewers, adding to the attractiveness of this platform. Sharing these videos can be equated to the online version of word by mouth marketing, extending number of people reached. Sharing videos creates six different outcomes: these being "pleasure, affection, inclusion, escape, relaxation, and control". As well, videos that have entertainment value are more likely to be shared, yet pleasure is the strongest motivator to pass videos on. Creating a ‘viral’ trend from mass amount of a brands advertisement can maximize the outcome of an online video advert whether it be positive or a negative outcome.
