The development of digital marketing is inseparable from technology development. One of the key points in the start of was in 1971, where Ray Tomlinson sent the very first email and his technology set the platform to allow people to send and receive files through different machines. However, the more recognisable period as being the start of Digital Marketing is 1990 as this was where the Archie search engine was created as an index for FTP sites. In the 1980s, the storage capacity of computer was already big enough to store huge volumes of customer information. Companies started choosing online techniques, such as database marketing, rather than limited list broker. These kinds of databases allowed companies to track customers' information more effectively, thus transforming the relationship between buyer and seller. However, the manual process was not as efficient.
Digital marketing is also referred to as 'online marketing', 'internet marketing' or 'web marketing'. The term digital marketing has grown in popularity over time. In the USA online marketing is still a popular term. In Italy, digital marketing is referred to as web marketing. Worldwide digital marketing has become the most common term, especially after the year 2013.
Market pioneers are known to often open a new market to consumers based off a major innovation. They emphasise these product developments, and in a significant number of cases, studies have shown that early entrants – or pioneers – into a market have serious market-share advantages above all those who enter later. Pioneers have the first-mover advantage, and in order to have this advantage, business’ must ensure they have at least one or more of three primary sources: Technological Leadership, Preemption of Assets or Buyer Switching Costs. Technological Leadership means gaining an advantage through either Research and Development or the “learning curve”. This lets a business use the research and development stage as a key point of selling due to primary research of a new or developed product. Preemption of Assets can help gain an advantage through acquiring scarce assets within a certain market, allowing the first-mover to be able to have control of existing assets rather than those that are created through new technology. Thus allowing pre-existing information to be used and a lower risk when first entering a new market. By being a first entrant, it is easy to avoid higher switching costs compared to later entrants. For example, those who enter later would have to invest more expenditure in order to encourage customers away from early entrants. However, while Market Pioneers may have the “highest probability of engaging in product development” and lower switching costs, to have the first-mover advantage, it can be more expensive due to product innovation being more costly than product imitation. It has been found that while Pioneers in both consumer goods and industrial markets have gained “significant sales advantages”, they incur larger disadvantages cost-wise.
During decline, demand for a good begins to taper off, and the firm may opt to discontinue the manufacture of the product. This is so, if revenue for the product comes from efficiency savings in production, over actual sales of a good/service. However, if a product services a niche market, or is complementary to another product, it may continue the manufacture of the product, despite a low level of sales/revenue being accrued. 
Strategic analysis is designed to address the first strategic question, "Where are we now?"  Traditional market research is less useful for strategic marketing because the analyst is not seeking insights about customer attitudes and preferences. Instead strategic analysts are seeking insights about the firm's operating environment with a view to identifying possible future scenarios, opportunities and threats.
Digital marketing planning is a term used in marketing management. It describes the first stage of forming a digital marketing strategy for the wider digital marketing system. The difference between digital and traditional marketing planning is that it uses digitally based communication tools and technology such as Social, Web, Mobile, Scannable Surface. Nevertheless, both are aligned with the vision, the mission of the company and the overarching business strategy.
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.
