Tony Stark decided there was no point in trying to hire a new secretary. Instead, he created his own “girl Friday” with a new A.I. program that would appear as a hologram of a young woman. Friday had a sweet, almost child-like disposition and was happy to show up whenever her boss needed her.
Friday was created by Mike Grell and Michael Ryan and first appeared in Iron Man Vol.3 issue 53 (2002).

As time went on, Tony began using Friday less and less. A couple of years later, she showed up again, angry and spiteful. Tony Stark was confused and then realized that Friday had evolved from having the disposition of a young girl to having the personality of a spurned teenager. She’d been abandoned and wanted some attention.
Tony Stark saw Friday as a child who needed to learn and be nurtured. With help of his butler Edwin Jarvis, he began raising Friday as a sort of adopted daughter.
More recently, Friday was brought back in a big way since Tony Stark started using her again as his primary 'girl friday'. In this role, she has to speak with a lot of big clients of Stark Industries.
