Yahoo had about a $30 billion market cap when Google was just getting started.
Read the book What Would Google Do?!
Their business models peaked at the right times and their brand is sticky because the technologies work. They make the complicated world of information on internet simple to navigate. Like the Apple products, it is a tool that anyone can use and feel good about. As long as you listen to your customers and the results continue to be positive, it is hard for anyone to take your market share... even Yahoo!
Perhaps there's another angle to approach this: "How have startups encouraged and enhanced the power of Google?"
Since inception, Google has acquired over 100 companies—many of which would be considered startups. These M&A's are a way for a large company like Google to onboard talent and IP that enhance existing products as well as extend their offerings. An example would be the acquisition of GrandCentral which ultimately became GoogleVoice. They have also acquired several smaller search engines that have gone on to enhance their core offering, as well as protect their market share.
The chief reason that I believe is in play is the monopoly. The term monopoly is often used to describe an entity that has total or near-total control of a market. For many years, Microsoft Corporation had a monopoly on the software and operating systems that are used in computers. In this scenario, an industry has many businesses that offer similar products or services, but their offerings are not perfect substitutes. In a monopolistic competitive industry, barriers to entry and exit are typically low, and companies try to differentiate themselves through price cuts and marketing efforts. Some examples of monopolistic competition include retail stores, restaurants, and hair salons. Companies that have patents on their products, which prevents competition from developing the same product in a specific field can have a natural monopoly. Patents allow the company to earn a profit for several years without fear of competition to help recoup the investment, high start-up, and research and development costs that the company incurred. Pharmaceutical or drug companies are often allowed patents and a natural monopoly to promote innovation and research. Usually, there is only one major company supplying energy or water in a region or municipality. The monopoly is allowed because these suppliers incur large costs in producing power or water and providing these essentials to each local household and business, and it is considered more efficient for there to be a sole provider of these services. Imagine what a neighbourhood would look like if there were more than one electric company serving an area. After a years-long drought, a wave of technology start-ups -- Uber, Lyft, Pinterest and more -- are going public, evidence that the sector is thriving. It is true that big tech companies helped create the current wave of start-ups. Cloud providers like Amazon Web Services make it possible for businesses to grow quickly without having to build their own server farms. , which specializes in a niche type of cloud computing, has benefited from distribution partnerships with Google and Amazon, helping it raise more than $180 million in its May IPO. Search engines, such as Google, may modify their search algorithms and policies or enforce those policies in ways that are detrimental to us. Apple has cracked down on this practice in its Safari browser, and Google has made moves to limit it on Chrome as well.
