During the 1960’s and 1970’s, commercialization of this technology had further impact on cell culture that continues to this day. Companies, such as Corning, began to develop and sell disposable plastic and glass cell culture products, improved filtration products and materials, liquid and powdered tissue culture media, and laminar flow hoods. The overall result of these and other continuing technological developments has been a widespread increase in the number of laboratories and industries using cell culture today.
