Influencer marketing represents a $10 billion industry in 2020 and is becoming of increasing relevance for many firms, especially those operating in a business-to-consumer environment. Few firms in the fashion, beauty, travel, food, or beverage industries are running marketing campaigns these days that do not include, at least to some share, a collaboration with popular users on platforms such as Instagram and TikTok. However, many marketing managers still have a less than adequate understanding of those platforms compared with their knowledge of more traditional media channels and often find it hard to make the right decision in this fast-moving environment. To provide some guidance in this respect, this article aims to give an introduction to the most critical platforms for influencer marketing. It then presents advice to firms who want to engage in influencer marketing as well as specific questions on identifying the right influencers to collaborate with.

A decade ago, we published an article in Business Horizons about the challenges and opportunities of social media with a call to action: "Users of the world, unite!" To celebrate its anniversary, we look at artificial intelligence and the need to create the rules necessary for peaceful coexistence between humanity and AI. Hence, we now are urging: "Rulers of the world, unite!" In this article, we outline six debates surrounding AI in areas like artificial superintelligence, geographical progress, and robotics; in doing so, we shed light on what is fact and what is Utopia. Then, using the PESTEL framework, we talk about the six dilemmas of AI and its potential threat and use. Finally, we provide six directions on the future of AI regarding its requirements and expectations, looking at enforcement, employment, ethics, education, entente, and evolution. Understanding AI's potential future will enable governments, corporations, and societies at large (i.e., the rulers of this world) to prepare for its challenges and opportunities. Then, we can avoid a scenario in which we return in 10 years to write the article: "Dreamers of the world, unite!"

This introduction to this special issue discusses artificial intelligence (AI), commonly defined as "a system's ability to interpret external data correctly, to learn from such data, and to use those learnings to achieve specific goals and tasks through flexible adaptation." It summarizes seven articles published in this special issue that present a wide variety of perspectives on AI, authored by several of the world's leading experts and specialists in AI. It concludes by offering a comprehensive outlook on the future of AI, drawing on micro-, meso-, and macro-perspectives.

Artificial intelligence (AI) is a topic in nearly every boardroom and many dinner tables. Yet, despite this prominence, AI is still a surprisingly fuzzy concept and a lot of questions surrounding it are still open. In this article, we analyze how AI is different from related concepts, such as the Internet of Things and big data, and suggest that AI is not one monolithic term but instead needs to be seen in more a more nuanced way. This can either be achieved by looking at AI through the lens of evolutionary stages (artificial narrow intelligence, artificial general intelligence, and artificial supper intelligence) or by focusing on different types of AI systems (analytical AI, human-inspired AI, and humanized AI). Based on this classification, we show the potential and risk of AI using a series of case studies regarding universities, corporations, and governments. Finally, we present a framework that helps organizations think about the internal and external implications of AI, which we label the Three C Model of Confidence, Change, and Control.

Since its first entry into the literature discussion in the 1980s, customer relationship management (CRM) has found its way into nearly every company. Concepts like personalization, loyalty programs, and customer valuation are used regularly to interact with and prioritize customers. Unsurprisingly, this more widespread use has changed our understanding of CRM substantially and as a consequence, the field has seen a remarkable transformation in the past 3 decades. Yet, the CRM strategies implemented by many firms today are frequently still fundamentally based on an understanding of CRM from the early days. The purpose of this article is to outline the origins of CRM and to present the main wisdoms that firms believed to be true about customers 3 decades ago. I then discuss the key insights that academics and managers have obtained in recent years that increasingly challenge those wisdoms. The article ends with an outlook of CRM in years to come and presents some of the major challenges practitioners and researchers will have to deal with in the near future.

In recent years, word-of-mouth (WOM) marketing has been the subject of considerable interest among managers and academics alike. However, there is very little common knowledge on what drives the value of WOM programs and how they should be designed to optimize value. Firms therefore frequently rely on relatively simple metrics to measure the success of their WOM marketing efforts and mainly use rules of thumb when making crucial program design decisions. This article proposes a new method to measure WOM program value that is based on the impact of WOM on the firm's customer equity. It then provides recommendations for the five main questions managers face when planning a WOM program: Who to target? When to launch the program? Where to launch it? Which incentives to offer? and How many participants to include?

Distance learning-that is, providing education to students who are separated by distance and in which the pedagogical material is planned and prepared by educational institutions-is a topic of regular interest in the popular and business press. In particular, MOOCs (Massive Open Online Courses), which are open-access online courses that allow for unlimited participation, as well as SPOCs (Small Private Online Courses), are said to have revolutionized universities and the corporate education landscape. In this article we provide a nuanced analysis of the phenomenon of online distance learning. We first provide an overview of its historical evolution, and subsequently define and classify key concepts. We further discuss in detail the optimal target group in terms of participating students and teaching professors and propose corresponding frameworks for driving intrinsic student motivation and for choosing a successful online teacher. We also outline the benefits that institutions can achieve by offering online distance learning. Finally, we speak about the specific connection between online distance learning and social media by focusing on the difference between MOOCs based on traditional lecture formats (xMOOCs) and connectivist cMOOCs.

Collaborative projects--defined herein as social media applications that enable the joint and simultaneous creation of knowledge-related content by many end-users--have only recently received interest among a larger group of academics. This is surprising since applications such as wikis, social bookmarking sites, online forums, and review sites are probably the most democratic form of social media and reflect well the idea of user-generated content. The purpose of this article is to provide insight regarding collaborative projects; the concept of wisdom of crowds, an essential condition for their functioning; and the motivation of readers and contributors. Specifically, we provide advice on how firms can leverage collaborative projects as an essential element of their online presence to communicate both externally with stakeholders and internally among employees. We also discuss how to address situations in which negative information posted on collaborative projects can become a threat and PR crisis for firms.

Britney Spears is one of the most successful female recording artists in contemporary music, world-wide. Herein, we analyze how Britney Spears and her team of employees rely on social media applications to communicate around this pop icon, and create and maintain her celebrity brand image. Specifically, we look at the use of social media during the launch of her single 'Hold It Against Me' and the associated album Femme Fatale in early 2011. The interplay of postings on Twitter, YouTube, and Facebook-combined with comments on her webpage, BritneySpears.com-can be seen as a prime example of social media usage to support new product introductions.

The concept of viral marketing has been discussed in the literature for over 15 years, since Jeffrey Rayport first introduced the term in 1996. However, the more widespread use of social media has recently pushed this idea to a whole new level. We provide insight into the relationship between social media and viral marketing, and illustrate the six steps executives should take in order to dance the social media/viral marketing waltz. We define viral marketing as electronic word-of-mouth whereby some form of marketing message related to a company, brand, or product is transmitted in an exponentially growing way-often through the use of social media applications. We consider the three conditions that need to be fulfilled to create a viral marketing epidemic (i.e., giving the right message to the right messengers in the right environment) and present four different groups of social media viral marketing campaigns (nightmares, strokes-of-luck, homemade issues, and triumphs). We conclude with five points of caution that managers should heed when trying to launch their own viral marketing campaign.

Micro-blogs (e.g., Twitter, Jaiku, Plurk, Tumblr) are starting to become an established category within the general group of social media. Yet, while they rapidly gain interest among consumers and companies alike, there is no evidence to explain why anybody should be interested in an application that is limited to the exchange of short, 140-character text messages. To this end, our article intends to provide some insight. First, we demonstrate that the success of micro-blogs is due to the specific set of characteristics they possess: the creation of ambient awareness; a unique form of push-push-pull communication; and the ability to serve as a platform for virtual exhibitionism and voyeurism. We then discuss how applications such as Twitter can generate value for companies along all three stages of the marketing process: pre-purchase (i.e., marketing research); purchase (i.e., marketing communications); and post-purchase (i.e., customer services). Finally, we present a set of rules-The Three Rs of Micro-Blogging: Relevance; Respect; Return-which companies should consider when relying on this type of application.

The concept of Social Media is top of the agenda for many business executives today. Decision makers, as well as consultants, try to identify ways in which firms can make profitable use of applications such as Wikipedia, YouTube, Facebook, Second Life, and Twitter. Yet despite this interest, there seems to be very limited understanding of what the term "Social Media" exactly means; this article intends to provide some clarification. We begin by describing the concept of Social Media, and discuss how it differs from related concepts such as Web 2.0 and User Generated Content. Based on this definition, we then provide a classification of Social Media which groups applications currently subsumed under the generalized term into more specific categories by characteristic: collaborative projects, blogs, content communities, social networking sites, virtual game worlds, and virtual social worlds. Finally, we present 10 pieces of advice for companies which decide to utilize Social Media.
