DVDs and Music CDs released on Tuesdays for several reasons.

Sales Figures are released on Monday

Consumers know when to look for new releases

If a Tuesday release is selling well, there still is time to order

more before the weekend.[3]

Shipments of music usually begin to arrive in stores on Thursday. That

gives the stores time to coordinate special midnight sales on Monday

evening, as opposed to Sunday, which is usually a shorter work day

This practice appears to have been followed for 20 years. :)
