According to Dublin-based market research company Research and Markets, product penetration for digital still cameras has reached at least 48% in the USA. Affordable and easy-to-use digital cameras have transformed how U.S. consumers use photography, changing it from something used to document important occasions like weddings and trips to an integral part of everyday life, the company notes in its new report, “Still and Video Cameras in the United States 2009”. The high penetration figure may indicate that the market is becoming increasingly saturated, and makes it challenging to maintain revenue growth.
