1)Is Safelite a monopoly? 2)Can Microsoft, with its 'HoloLens,' retain its digital monopoly and repeat the history?

1)Yes, Safelite is becoming a monopoly.

Safelite is a company providing vehicle glass repairs, replacement, and calibration services and insurance claim Management Company. It has built close relationships with the big auto insurance companies. Safelite can charge a lower price than the other firms in the market. The insurance companies also deal with Safelite for the business rather than the other firms as it has the most significant market share. And now with this big market share and dealing with big insurance companies, it is the Claims Administrators for the complaint in the auto glass market. So as a complaint of auto glass repair is filed, it gets directly in the Safelite call center.

2)HoloLens by Microsoft is a pair of sunglasses manufactured and developed by Microsoft. Recently HoloLens 2 was announced by the company in February 2019.

When something new is invented by any company then other companies try to make some changes and copy their products. They try to represent it as something new in the market. Selling the same product by just giving it a new brand name will not make it unique. Close substitutes for HoloLens will be available in the market, which might create an oligopoly. Therefore, Microsoft is a company that always tries to innovate and bring something new and completely different in the market. HoloLens is one of the most recent innovations by Microsoft which may or may not retain its digital monopoly.
