MediaMark Research

In order to use the MRI+ you need to register using your UCB e-mail address (.berkeley.edu). 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 berkeley.edu, 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.

When registering you do not have to use your personal address and telephone number, use the following instead:

Address: Business Library
University of California
Berkeley, CA 94720
Telephone: 510-642-0370
