Progressiveness of Expedia Commercials

Expedia Commercial
Expedia's Valentine's Day special commercial showed a bunch of scenes where people were kissing in public. 95% of the couples kissing were heterosexual, until about (0:22) where there is 2 women that kiss each other. This shows the progressiveness of commercials in the media. Not too many years ago, there were very rarely commercials casually displaying homosexual relationships.
