Dr who never ran consecutivley it always got cancelled and rerun and spun off and remade, same with star trek none of its series or spin offs went longer than a few years.
The original Doctor Who series (1963-1989) ran for consecutivley for 26 seasons. It was only cancelled once, which was in 1989. To this day it remains the longest running Sci Fi series.
As for Stargate, its a shame its cancelled, though I don't think SG1 could go on for much longer anyway. Still if nothing else happens with continuing SG1 at least Stargate should continue in Atlantis and other future spin offs.
