What was the first romantic kiss between two men ever aired on nationwide commercial primetime US television?

It seems a bit of TV history has been forgotten. In the wake of Luke and Noah (lovely boys) I feel the need to bring up dear ol' Jack McPhee from Dawson's Creek. The kiss between Jack (Kerr Smith) and his crush Ethan (Adam Kaufman) was the very first gay male kiss aired (in a drama) on prime-time television.
