Rentrak Corporation (Nasdaq: RENT), a leader in multi-screen media measurement serving the entertainment and advertising industries, released the "Stickiness" Index for the week of October 5 through October 11, 2009. The "Stickiness" Index lists the top-25 "stickiest" 30-minute, 60-minute and 120-minute primetime programs based on proprietary information derived from Rentrak's TV Essentials service which tracks anonymous set-top-box viewing information.

The "Stickiness" Index is based on the average percentage of the program viewed, divided by the average percentage viewed for all series of that duration during Monday-Saturday primetime (8pm-11pm) and Sunday primetime (7pm-11pm). Programs with the most engaged viewers will have higher "stickiness" indexes.
