On March 28, 2011, The New York Times website became a restricted site where most of the content was protected behind a "paywall." Users who exceeded the limit of 20 free articles per month were required to pay for either a digital or print subscription. The newspaper industry had been suffering from revenue declines over the past decade, and the transition to digital media was difficult to navigate. Revenues from online advertising were not sufficient to replace the loss of print revenue, and many publishers had explored charging readers for content, with mixed success, where specialized sources like The Wall Street Journal were successfully using the model, but several other general news sites had failed. Newspapers and content creators in general were very interested in understanding whether transitioning to the paywall at the most popular news website would succeed, and whether it could become a blueprint for future success as a sustainable business model. There were several difficult issues to examine in determining the digital strategy for The Times. Would consumers remain as engaged with a site protected by a paywall? Would advertisers react positively to such a move that walled off readers? Would readers value both the print and digital versions of the content, or would it become necessary to create new content? The Times had several choices in designing the paywall, including determining the digital content, pricing, as well as how to interface with readers of secondary news websites like blogs that posted links to news articles. Should they design a "leaky" paywall where determined users could easily slip through, or a "bulletproof" paywall like the Financial Times had done, where users had to pay before they could access any content? What choices would provide the foundation for a successful business model?

PatientsLikeMe (PLM) is an online community where patients share their personal experiences with a disease, find other patients like them, and learn from each other. The company was founded by Jamie and Ben Heywood when their 29-year-old brother was diagnosed with ALS or Lou Gehrig's disease. In less than five years, PLM has grown to 15 patient communities where over 80,000 patients discuss 19 diseases. In December 2010, PLM is discussing its planned launch of a General Platform that would expand the number of diseases covered from 19 to over 3,500. Is it the right move, and what does PLM need to do to make it a success?

In September 2010, faced with increasing threat from social game companies such as Zynga, Ben Feder, the CEO of Take-Two Interactive Software. Inc., had to decide the long-term strategy of his video-game company. As a publisher of traditional video games for Xbox 360, PlayStation 3 and Nintendo, Take-Two had several popular video games, such as Grand Theft Auto, to its credit. However, the video game industry was undergoing a major transition. In addition to digital downloading and cloud gaming, casual and social games were transforming the video game industry. Electronic Arts, one of Take-Two's major competitors, acquired a social gaming company in November 2009 for $400 million. In August 2010, Disney bought another social gaming company for $763 million. Social games were developed, marketed and monetized very differently from traditional console games. Should Take-Two follow the lead of its competitors or continue to focus on its core business?

In January 2010, Jen McDonald, head of Bank of America Corporation's (BoA) Digital Marketing group, was discussing the bank's mobile strategy with Douglas Brown, senior vice president, Mobile Product Development. BoA launched mobile banking in 2007 and within three years it had 4 million active customers.

Jen and Doug had to decide how to leverage the mobile platform for various businesses of the bank without creating confusion or increasing complexity for the consumers. Recognizing the potential impact mobile technology could have on the entire banking industry, they also had to decide on how to position BoA's mobile banking in the long run.

In January 2010, YouTube, the world's largest online video aggregator, was still seeking to become profitable. Was the time right for Google, YouTube's parent company, to charge users seeking to upload content, as some analysts had suggested - and if so, who should be charged how much and for what? Could YouTube charge users for downloading content, a model it was now beginning to test? Or would it be better for the online video giant to continue to pursue an advertising model, but perhaps broaden its services to advertisers?

Backchannelmedia (BCM), a three year old start-up, intended to completely disrupt the world of advertising by transforming the way Americans watched television. BCM had developed a technology to make television "clickable," enabling viewers to interact with the content on their television screens. By April 2009, BCM had conducted consumer studies and field tests and the results were very promising. However, the industry was dominated by large players who could impede the introductions of new technologies. BCM's founders would have to make critical decisions about how quickly to roll-out their technology, and to whom. Which industry players were allies? How would BCM monetize the value they would create? Would investors see as much potential in BCM as its founders? And how would the company's cash constraints impact the strategy in the current economic environment?

In May 2008, the new CEO of Cyworld, a social network company in Korea, had to decide how to create and capture value from his rapidly growing user base. Cyworld was founded in 1999 and in 2003 it was acquired by SK Telecom, a leading mobile service provider in Korea. By 2007, Cyworld had 21 million users and $95 million revenue--$65 million from paid items (music, virtual gifts, etc.), $15 million from mobile networking, and $15 million from advertising. The new CEO had to decide which of these three revenue sources he should focus on in the future and how this choice would influence the target customers, the service offerings and the required capabilities.

Free customers who are subsidized by paying customers are essential to a vast array of businesses, such as media companies, employment services, and even IT providers. But because they generate revenue only indirectly, figuring out the true value of those customers - and how much attention to devote to them - has always been a challenge. Traditional customer-valuation models don't help; they focus exclusively on paying customers and largely ignore network effects, or how customers help draw other customers to a business. Now a new model, devised by professors Gupta, of Harvard Business School, and Mela, of Fuqua School of Business, takes into account not only direct network effects (where buyers attract more buyers or sellers more sellers) but also indirect network effects (where buyers attract more sellers or vice versa). The model calculates the precise long-term impact of each additional free customer on a company's profits, factoring in the degree to which he or she brings in other customers - whether free or paying - and the ripple effect of those customers. The model helped an online auction house make several critical decisions. The business made its money on fees charged to sellers but recognized that its free customers - its buyers - were valuable, too. As competition heated up, the company worried that it wasn't wooing enough buyers. Using the model, the business discovered that the network effects of buyers were indeed large and that those customers were worth over $1,000 each - much more than had been assumed. Armed with that information, the firm increased its research on buyers, invested more in targeting them with ads, and improved their experience. The model also helped the company identify the effects of various pricing strategies on sellers, showing that they became less price-sensitive over time. As a result, the company raised the fees it charged them as well.
