Which one has been able to eek out squeeze and drain the lifeblood out of being on TV for 4 years the most?
Please see information here
Shannon Dougherty

Star Trek
http://en.wikipedia.org/wiki/Star_Trek#Star_Trek:_The_Original_SeriesStar Trek debuted in the United States on NBC on September 8, 1966.<3> The show, starring William Shatner as Captain James T. Kirk, told the tale of the crew of the starship Enterprise and that crew's five-year mission "to boldly go where no man has gone before." After only three seasons, the show was cancelled and the last episode aired on June 3, 1969
Now before you answer this incredibly important question perhaps we need to index or weight this considering the vast Roddenberry juggernaut of TV film and publishing versus Ms. Dougherty ....and her star power.
