I would argue further that it is correctly named. Our video poster,
whether explicitly specified by poster= attribute, or implicitly by the
behavior defined in the html5 spec, stands firmly in the tradition of
movie posters and even vaudeville posters:


In my own personal experience, movie posters did indeed entice me to
plunk down my $2 (American) in order to gain access to a seat inside the
Orpheum theater. Or, they didn't grab me, so I moved down the street to
examine the poster at the Lyric. The difference today is that we have
technology to include people who can't see posters or movies, whereas we
had no such technology back in the days of Cary Grant and Marilyn
