When did window tinting get popular?

Window tinting gained popularity in the 1960s and 1970s, particularly in the automotive industry, as car manufacturers began to offer tinted Windows as a factory option. The trend was driven by a growing awareness of the benefits of tinting, such as heat reduction, UV protection, and privacy. By the 1980s and 1990s, residential and commercial window tinting also became more common as energy efficiency and aesthetics became focal points for building design. Today, window tinting is widely used across various applications, including vehicles, homes, and offices.
