Donovan made her first YouTube channel in September 2005 and uploaded her first video, "Introducing LisaNova," a reel of facial clips in black-and-white accompanied by the Charles Aznavour song Non, je n'ai rien oublié, to YouTube on June 7, 2006. She has parodied a number of celebrities and public figures; her impersonation of Sarah Palin was praised in Wired as "ruthlessly hilarious", and in 2008 Ralph Nader made a guest appearance in one of the skits. In a Forbes magazine article, YouTube founder Chad Hurley highlighted Donovan's success as an example of the changing paradigm of entertainment. Donovan is also a co-creator of the popular YouTube channel 'The Station', which led to her co-founding the YouTube network Maker Studios.
