Hey guys, So I was wondering, CDs are mostly released on Tuesdays (? i think) and Movies can be released on Thursdays but usually Fridays. The Apple iPhone is being released on a Friday. Why is there a difference? I would think everything should be released on a Friday and ad campaigns should be most rigorous on a Thursday. Why do some products have different dates? ---

CDs and DVDs are released on Tuesdays because that is a retailers slowest day and it is an effort to get people into the stores. Movies are released on Fridays because weekend ticket sales are heaviest and it gives them a jump on sales before the hype goes down. I-Phone on a Friday? Beats me. ---

Another major reason CD’s and DVD’s are released on Tuesday is that Billboard Magazine, the highest profile journal for music, starts its chart sales week on Tuesday. Since blockbuster CD/DVD releases have their biggest sales in the first week, a Tuesday release maximizes sales and thus chart performance. ---

A lot of Apple gadgets are announced on a Tuesday. I’m not sure why the iPhone was realsed on a Friday, but I know the time was set to 6PM so less people would take off work to get one. I think comic books usually come out on Wednesday Brian
