Because a standard monthly comic is around 22 pages long, it equates to five or six issues. When a publisher expects to release numerous collections in a series, they will frequently title them Volume 1, Volume 2, Volume 3, and so on. In the case of The Amazing Spider-Man, there have been nine volumes to date. Each volume has been titled for what type of content it contains: "Origins", "Legacies", "Sons", "Ties", "Bloodlines", "Hopes &; Dreams", "Future Shock" and "Last Issues". The first four volumes were released under the Marvel Comics label, while the last five are published by Image Comics. However, both companies have collaborated on certain projects over both labels. For example, TASM artist Steve Ditko contributed art to the Origins volume 4 story "The Return of the King". Image has also collaborated with other publishers on projects involving their characters. "The Sinister Six", which features members of both Marvel's and DC's versions of this villain team, was published by IDW Publishing. This crossover event was followed by two mini-series that concluded the storyline. Spider-Man has also appeared in other media besides comics. A television series based on the character premiered in 1977 and ended in 1981.
