Vivitar was the leading brand name of a manufacturer, distributor and marketer of photographic equipment founded in 1938 that operated out of Oxnard, California, USA. The Vivitar brand was introduced in the 1960ies, and became in the 1970ies associated with a series of high quality lenses labelled Vivitar Series 1, and a very successful line of auto thyristor flash units. After the death of the original owners, the company went into decline, and eventually bankruptcy. The Vivitar brand was acquired in 2008 by Sakar. Sakar has revived the Vivitar brand. However, the quality of the current crop of Vivitar-branded products is not very good and not on par with Vivitar's legacy.
