When Microsoft announced that it was abandoning its own EdgeHTML rendering engine in favor of rebuilding the browser around Chromium, there was a mix of trepidation and hope among Windows users and Edge fans. On the one hand, the company decided to scrap years of work done on EdgeHTML to start anew, potentially alienating the browser's small but loyal base. On the other hand, the move to Chromium, if done right, gives Microsoft a more mature platform to build on, improving compatibility while bringing over some of the now-old Edge's most-loved features. In a recent piece by Windows Central Senior Editor Zac Bowden, he argued that Edge built on Chromium "might give Google Chrome a run for its money", and early leaked builds of the browser certainly show promise (see video below). But, in order to truly challenge Chrome's utter dominance of the browser market, it won't be Microsoft fans and consumers that decide Edge's fate. Rather, Microsoft will have to work hard to win over IT departments, according to sources we spoke with for this story.

Two of the top firms that track browser stats, StatCounter and Net MarketShare, say Chrome currently commands between 66 percent and 71 percent of the desktop browser market, depending on which company's stats you go with. By comparison, Edge currently controls just over four percent of the market, while Firefox comes in at a little under 10 percent. In other words, Chrome absolutely dominates right now. It wasn't always this way, however. Microsoft's previous flagship browser, Internet Explorer (IE), was the frontrunner for more than a decade leading up to Chrome's launch in 2008. It wasn't universally loved, to be sure, and frequent frustrations with IE were what caused Firefox to gain a healthy following as an alternative before Chrome arrived. Chrome absolutely dominates right now. As Chrome gained mindshare, tied the browser to its broader ecosystem, and built out a broad catalogue of extensions, it gradually managed to climb to the current top spot. Microsoft's virtual abandonment of IE (it still lives on, for now, for legacy support) and switch to Edge with Windows 10 accelerated Chrome's rise as the newer browser. As IE faded into the background, IT departments began looking to Chrome as their browser of choice. Long a bastion for IE, portions of the enterprise sector gradually made the shift to Chrome, based on its maturity as a platform and security. And as web apps have started to become an increasingly important part of the business world, Chrome positioned itself as a fast, secure solution for business needs. From a recent Google-commissioned report by research group Forrester on the economic impact of deploying Chrome in the enterprise: Chrome is now being deployed more by organizations due to the additional business solutions and features that it offers. With Chrome Browser, organizations can provide IT teams with more control to govern their employees' internet use, to standardize processes that can be managed centrally, and to increase security in protecting the company data from malware and phishing attacks. In 2017, Google introduced Chrome Enterprise, further pushing the browser's business chops, along with those of its broader Chrome and cloud ecosystems. Courting the IT crowd

Many consumers rarely take enterprise scenarios into account, preferring instead to focus on things like "browser wars," but the sector is incredibly important to both Microsoft and Google. More importantly, businesses are slow to change. And it's IT groups, not individuals, that will be some of the key decision makers in the new Edge's success, according to Steve Kleynhans, vice president for mobile and endpoint at analyst firm Gartner. "IT organizations run on inertia," Kleynhans said. "They don't like to change anything from the way that it's working today." And that is precisely the challenge Microsoft faces with businesses and, subsequently, a large portion of the browser market. "[IT departments] only grudgingly moved off [Internet Explorer] towards Chrome, and it's going to be really hard to push them off of Chrome to something else," Kleynhans said. Microsoft will have two main routes of courting businesses, according to Kleynhans. Either the company will have to provide something that is so invaluable that they can't ignore it, or make the process of moving over to the new Edge so simple that it can be done almost without realizing it. Security will be a major piece of the puzzle for Microsoft. Security will be a major piece of the puzzle for Microsoft, Kleynhans said. It won't be a "cool" new feature that garners attention. Rather, the company will have to demonstrate that Edge is more secure in some way. On the other side of things, making the browser easy to adopt, part of Microsoft's job is already done: it comes with Windows. The reason that didn't work with the old Edge is that the browser just "didn't work very well," Kleynhans says. "If Edge does the basics, if it doesn't break their websites [and] everything keeps working the way they want it to, it becomes easy for them to slide into it." According to Kleynhans, Microsoft could gain traction over the long-term by focusing on that second track: making the switch as seamless as possible. But if the company is looking to push the new Edge on the business side of things much more quickly, it will have to present a compelling reason for why it is more secure. Opportunity in change
