Car insurance is an incredibly competitive market. Because auto insurance is a necessity in order to operate a vehicle in this country, there are few ways to create new demand; a company must either attract new drivers immediately or take existing business from another company. Some car insurance companies, like Geico, pay a huge amount toward advertising each year in order to attract customers; other companies prefer a different approach, focusing its budget and staffing on licensed agencies that will push the policy to consumers.

An interesting thing to note about car insurance is that there are very few new companies selling car insurance. Every major car insurance company has been in operation for more than half a century. Additionally, over half of the insurance market is dominated by the top five car insurance companies; while there are independent or local insurance companies, the handful of major corporations are the best known and most powerful within the industry.

Who are the Top 10 Car Insurance Companies?

Employing slightly more staff than Geico, Progressive nevertheless functions along a similar path: By focusing its attention on advertising, Progressive can lure in most customers without needing to rely heavily on agencies.

What makes Progressive especially unique in the marketplace is its forward-thinking corporate mindset and tendency to think outside of the box. Progressive was one of the first companies to introduce a pay-as-you go auto insurance policy; it was also the first company to provide competitor’s quotes on its own website.
