Mark Arnold Krinsky (born October 25, 1954), better known as Ed Powers, is an American pornographic film director, producer, actor, and radio host.

In 2001, Sunrise Adams made her debut in More Dirty Debutantes 186, though she later referred to the experience of making the film as "nothing [she] want[s] to remember".

[14] Powers hosted a late-night weekend radio talk show on 97.1 KLSX in Los Angeles, known as Bedtime Stories, in which various guests connected with sex in some way; the show hosted swingers, prostitutes, and porn stars, who would talk with Powers about sex and take listener calls.

His co-host was a young Latina woman named Elizabeth who had performed in a number of his films under the pseudonym Bonita.

[15] Powers was severely hit by the global financial crisis in 2008, and his home in the Granada Hills neighborhood of Los Angeles was foreclosed by Wells Fargo.
