MediaMark Research

In order to use the MRI+ you need to register using your UCB e-mail address ( You will then be recognized as a UCB student, faculty, or staff member. If you do not have a UCB e-mail address that ends in, it will not be possible for you to use MediaMark. After registering, you will be sent an e-mail from MRI asking you to validate your account. Once this has been done, you will have access to the data tables.
