the same day they go on sale
looks like not all of the remaining Hollywood studios are putting the 30-day brakes on providing movies to Redbox, as Paramount has concluded after a ten month study that it has "minimal" effect on DVD sales. Dennis Maguire, President of Paramount Home Entertainment says the the company is "allowing the consumer a choice of how to consume our movies while maximizing the profitability of our releases in the home entertainment window" while Redbox prez Mitch Lowe looked forward to joint marketing programs. That puts another studio on deck to provide the Blu-ray rentals we're expecting to see later this year and is a pretty sharp contrast to recent deals with Fox and Warner delaying low cost rentals to protect their day one sales and premium rentals on video on-demand.
