Buffy
Okay, WWBD. What would Buffy do? Huh?
When Supernatural started, comparison to the successful Joss Whedon shows Buffy and Angel were inevitable. Like them, Supernatural featured ordinary people fighting the Supernatural, and it also aired on The WB where Buffy had started and Angel had aired until it finished in 2003. An early review of the Pilot described Supernatural as "new X-Files meets the OC, meets Buffy type show from the WB" Source (yeah we have no idea where The O.C fits in either !)
Supernatural certainly attracted many viewers who had also been fans of the Whedon show. This can particularly be seen in Supernatural/Buffy Crossover crossover fanworks. The pairing of Dean with the rogue slayer Faith.
Buffy fandom invented the term Jossed - to be jossed is to have fan theories or events in Fanfic be invalidated by new canon in the Show. By contrast Kripked was a term coined in Sueprantural fandom to refer to having fan theories supported by canon. See also Fan Fic Cliches
in terms of staff the most famous to crossover between the saeries is Ben Edlund. Ben started working with Joss on Firefly before moving to Angel for the last couple of seasons. He wrote and directed the Hugo nominated episode Smile Time aka the one where Angel gets turned into a puppet.
