The Harvard Business Review (HBR) Group was an early adopter of social media, boasting a robust presence on Twitter, Facebook, and LinkedIn. Now the company is seeking to evolve the Group's efforts from social media to social strategy - and start moving both revenue generation and strategy integration into HBR's core. To that end the company created two parallel projects, each tasked with developing two concrete new offerings that leveraged social dynamics on social platforms, while at the same time creating revenues or slashing costs for HBR. Now it has to choose between four different projects.

American Express has developed a number of strategic partnerships with Facebook, Foursquare and Twitter to improve their card members experience and lower its customer acquisition cost. The case details the history of these partnerships, examines American Express' own social platforms, and talks about American Express' future plans in the realm of social strategy. It then presents students with two options related to Amex's future options and asks them to pick one.

Following the lean years of the Great Depression when bankruptcies proliferated and financing for new ventures virtually dried up, new demand for capital was created in a post-War environment of scientific and industrial expansion. Venture funding occurred more widely in the United States than it ever had done before. While the roots of the American venture capital industry are long-standing and multifaceted, they are frequently traced back to the pioneering initiatives of the French General and Harvard Business School professor, Georges Doriot, who established the American Research and Development Corporation (ARD) in 1946.

In October 1945, Henry Ford II received a telegram in his office at the Ford Motor Company in Dearborn, Michigan written by Charles "Tex" Thornton, a U.S. Air Force colonel. The telegram presented an opportunity for Ford to deploy a system of statistical control which had been developed and applied successfully in the management of the Army Air Forces. Henry Ford II had recently assumed control of his grandfather's troubled automotive empire, and was looking for experienced auto industry men to help him make Ford a dominant name once again. Thornton had no industry experience whatsoever, but seemed convinced that his ideas could be applicable to Ford's company. Perhaps the Ford Motor Company could use an injection of new ideas. Hiring Thornton and his men could end up being Ford's most inspired move. Or his most disastrous.

The cofounders of foursquare are deciding how to respond to competitive threats and scale up the organization. Foursquare was a location-based online service that allowed users to "check in" to a location using an application on a smartphone. Foursquare kept track of a user's check-ins, shared them with users' friends, and unlocked "Specials" that gave users discounts at nearby locations. Within a year and a half of its founding the company had 45 employees and over 5 million users and was valued in excess of $100 million. However, many competitors, including Facebook, Twitter, and Yelp, developed competitive services requiring foursquare to respond.      

Wilbur (1867-1912) and Orville (1871-1948) Wright were fascinated by the mystery of flight and they built on the ideas of prominent earlier figures such as Octave Chanute (1832-1910) the French-born American who was influential in fostering the free exchange of ideas surrounding aeronautics. Information exchange between practical tinkerers from across the globe led to a process of cumulative innovation unhindered by rivalry operating through the intellectual property rights system. Yet in 1903, the year the Wright Brothers achieved controlled sustained flight at Kitty Hawk, North Carolina, they applied for and were subsequently granted a US patent for a "flying-machine" which changed the industry irrevocably. While American manufacturers diverted resources from science and technology to patent wars and legal disputes, European aeronautics advanced more rapidly.

Henry Phipps, Jr. made his fortune in the steel industry alongside one of America's most celebrated entrepreneurs - Andrew Carnegie. His wealth was administered in the form of trusts, which he hoped would provide a stream of income for his family and their descendants into the future. Phipps had a clear vision for the intergenerational disposition of his assets, which required both an efficient organizational structure for the wealth to be administered and leadership on the part of family members to keep his original vision intact. Despite undergoing several significant legal and leadership changes, the trusts survived relatively intact and continued to achieve their express goal of preserving the capital Phipps created and providing income for Phipps family members.

CEO is deciding between international expansion and increasing the number of publishers to strengthen the company's advantage in the mobile advertising industry. AdMob displayed advertising on global devices, and powered 6,000 websites and 1,000 applications, and served over 6 billion advertising impressions a month to 25 million unique visitors. AdMob's success attracted numerous competitors, such as Millennial Media and Quattro Wireless, both of which were expanding quickly and had raised considerable capital. The company now needs to allocate its limited resources wisely to position it for long-term success.

In January 2010 Mark Pincus is deciding how to double the number of Zynga games' players to 500 million without sacrificing profitability. These ambitious growth plans required changes to product, corporate strategy, and customer acquisition and retention. With regard to product Pincus needed to decide to invest in evolving the successful games or develop new games. With regard to corporate strategy, Pincus had to choose whether each game should compete on its own, or force every game to build functionalities that support other Zynga games too. Finally, to ensure customer acquisition and retention Pincus faced the choice between deepening commitment to Facebook or developing its own distribution channels.

In 2008, the U.S. financial system was in a state of crisis and Lehman Brothers went from a major Wall Street investment bank to an insolvent institution. It was a swift end for a firm that had its beginnings over 150 years prior. What would be the firm's legacy? And how, if at all, had its activities changed the course of American history?

Twitter is a micro-blogging company that allows users to send short text updates to others. The site is used by people, including celebrities, government officials, and businesses. It helps to raise money for non-profit organizations and provides first-responders with information during a natural disaster. Even though almost 10 million people visited the site in early 2009, the site had no strategy for monetizing the traffic. The case allows students to examine potential monetization strategies for Twitter.

Meetup, an on-line company providing means of arranging face-to-face meetings, is deciding between two options of increasing its revenue by investing to: (i) increase new sign ups, (ii) improve the engagement of existing users.

In October 1941, a top secret envoy from the U.S. military was sent to Crosley Corporation in Cincinnati, Ohio to request their assistance to construct a weapon that would drastically strengthen the defenses of U.S. troops: the proximity fuze. Such a fuze would allow enemy aircraft to be shot down with a rate of accuracy well above that of previous weaponry. The task would be a challenging one, as conventional wisdom held that it took at least four years for a weapon to go from concept to production, whereas the proximity fuze was needed on a shorter time frame. Moreover, the production process would be complex, requiring hundreds of components produced by dozens of manufacturers, all of which Crosley would have to assemble to produce the finished product. Would Crosley accept the assignment?

In 1929, Chicago, IL mob boss Al Capone was at the height of his power. As head of the extensive crime organization known as "The Outfit" during most of U.S.'s Prohibition Era (1920-1933), Capone oversaw hundreds of brothels, speakeasies, and roadhouses which served as venues for gang-administered gambling, prostitution, and illegal alcohol sales. At their peak, yearly revenues from all of his enterprises combined totaled over $100 million. Capone's ability to operate these establishments with impunity stemmed from a combination of his political ties and a profound fear of reprisal. Capone's ascension had come at the tremendous loss of human life. Turf wars between Chicago gangs had caused roughly 700 gang-related deaths from 1920 to 1930. By some estimates, Capone had been directly or indirectly responsible for over 200 murders, the most notorious of which was the St. Valentine's Day Massacre in February 1929, a shootout that had killed seven men from a rival gang. The brutality, efficiency, and wealth of Capone's organization demonstrated the destructive forms of American entrepreneurship in the early 20th century.

From 1995 to 1999, the U.S. experienced a period of tremendous growth in its information technology (IT) sector. The IT industry, although it accounted for less than 10% of the U.S. economy's total output, contributed disproportionately to economic growth. One market that was particularly contentious was online pet supply retailing. Pet supply retailing had an estimated worth of $31 billion in 1997, and in the late 1990s, several startups and brick-and-mortar-based companies launched online retail stores, hoping to become the premiere (and perhaps the only) online pet supplies retailer. Two companies emerged as pure play frontrunners: Oakland-based Petstore.com and San Francisco-based Pets.com. In the years that followed, online pet supply retailers were widely regarded by the media as epitomizing the excesses and the follies of dot-com speculative mania in the late 1990s that culminated in the 2000 stock market crash. In 2008, CNet pronounced Pets.com as one of the greatest dot-com disasters in history. But what led to the failure, and subsequent crucifixion, of these one-time media darlings? Were Petstore.com and Pets.com the victim of poor strategic decisions, a prohibitive and crowded market, investor attitudes that destroyed their chances of success, or perhaps just bad luck or bad timing?

Zopa, a U.K.-based peer-to-peer lending company, connected individual lenders and borrowers via an online interface. The company charged a small fee for completed loan transactions but has not turned a profit. Zopa offered two platforms, Markets and Listings. Markets was an automated system that assembled loans by combining lowest loan offers from different Zopa lenders. Zopa Listings allowed prospective borrowers to post eBay-like listings explaining who they were, how much money they needed, and how they would use it. Lenders then made offers specifying how much they were willing to lend and at what rate. Neither platform met with much success. In February 2009, the CEO of Zopa is considering withdrawing from Listings, and focusing on Markets, even though a company in the U.S., Prosper, had attracted many users with a product akin to Zopa Listings.

Yelp was a popular on-line destination for reviews of local establishments, written by volunteer Internet users and read by 20 million people per month. However, the company made meager profits. The CEO needs to decide between two options to increase the revenue. First, the company can maintain its existing monetization model and quickly build a massive sales force to enroll many local business owners as advertisers and sponsors. The second option was to change the monetization model completely and charge readers for access to Yelp reviews.

Updates the (PRODUCT) RED (A) case through early 2008, including announcements of new partner relationships (with Hallmark, Microsoft, and Dell) as well as new communications initiatives.

Describes the launch and initial results of the (PRODUCT) RED campaign, a social marketing initiative conceived of by U2's Bono and Bobby Shriver to combat AIDS in sub-Saharan Africa. The company licensed the (RED) brand to partner companies, which initially included Gap, Apple, Motorola, Armani, and American Express. The business model was structured to benefit partner companies by increasing consumer purchases - of (RED)-branded products such as red iPods and phones - while also resulting in increased donations to the Global Fund.
