Turn on your computer and go to IMDB.com. On the front page you will see thumbnail photos from videos with an invitation written above urging you to watch new videos and trailers. Click on that invitation to be taken to a page that features a short list of episodes, movies, clips and trailers.
Look to the left side of the page beneath the large yellow IMDB logo. Notice the clickable list there. You will see another a link to full-length movies and full-length television shows.
Click on the full-length movies link to be taken to another page that lists all the movies available for online viewing on IMDB. The movies are listed in alphabetical order. Click on the title of the movie to be taken to that movie's IMDB page. Beneath the title you will see a thumbail over which is written "full movie." Click on this to be taken to another page on which the movie will start. The video is free to watch, and there will be limited commercial interruptions. To the right of the player's screen are links to other full-length videos related to the movie you are watching--by the same director, actors or subject matter.
Clicking on the full-length TV episodes link takes you to the list of television shows that IMDB offers for viewing. The TV shows are also presented in alphabetical order. When you click on the title of the show, you are also taken to that show's regular IMDB page. Instead of just one thumbnail that links to the video player, there may be three or four. Above that will be the word "videos," followed by a parenthetical indication of how many different episodes are available for viewing. Clicking within the parentheses takes you to the page from which you pick the particular episode you want to watch.
