Our Story

Today, we continue to innovate while staying true to our core principles—rejecting advertising and maintaining independence—so users can be confident in our unbiased insights.
Over 50 Years of Consumer-Driven Work
CSS was founded on a simple yet powerful idea: consumers deserve access to independent, unbiased information to make informed decisions. While ratings are standard today in an era of instant information, that wasn’t the case in 1974, when much of the information we now take for granted was unavailable to the public.
