Batman (1989)
Answer: In addition to the other answers, it may also be a factor that around this time the "current" Robin, Jason Todd, wasn't very popular, to the extent that a phone poll was taken which ended up with him being killed off not long before this film was released. Batman was Robin-less in the comics from 1988 - 1991. Given Robin's lack of popularity and strong association with the Adam West Batman series, the filmmakers may well have felt that a clean slate would be a better approach.
Answer: Probably because this was the first movie in the series. It sets up the entire Batman premise and goes into Wayne's backstory before he met Robin. Adding Robin at this point would only clutter and confuse the plot. It would also slow the action and diminish the conflict between Batman and the Joker. Robin being introduced later allows for his own history to be better incorporated into the overall story.
Answer: According to screenwriter Sam Ham, Batman started out solo in the comics.
