Kevin & Scotty's Wedding

Last night's gay wedding on Brother's & Sisters is considered by some to be the first on-air marriage of major characters in television history. However, I'd always thought that Pedro Zemora and Sean Sasser's 1994 commitment ceremony on MTV's Real World was the first. But I can see the argument made that MTV wasn't/isn't a "major" network or that Pedro and Sean weren't "characters" but an actual real life couple.
