Part of the gradual shift we're seeing towards more data and computation intensive and media-rich science is the greater use of supplementary files as adjuncts to primary research articles. The OhioLINK Electronic Journal Center now displays any accompanying material included in Institute of Physics and Elsevier articles as "Supplementary Files" below the abstract. The available files include videos (.mov, .avi and .mpeg formats), PDFs and PowerPoints. All files sent to OhioLINK by publishers are made available.
Here's a good example:

Many Cell articles also contain supplementary files, for example:
