May 19, 2003 Jane Magazine has launched a series of promotional contests that require readers to purchase an advertires' product - and to prove to advertisers that magazine ads do drive business, The Wall Street Journal reported on Friday.

Readers who want to participate in an article writing competition must buy products affiliated with the promotion. They then enter the Universal Product Code from those purchases on the magazine's Web site. Readers are allowed to enter the contest more than once - provided they buy more products and have more products code to enter on the web site.
