Java Reader Report March, 2017 March 2017

To Whom It May Concern:

In November 2016, Erdos & Morgan was retained to conduct an online survey sponsored by Java Magazine. The study collected information regarding readership of Java Magazine, other publications read, business and professional information, and demographic information.

The survey sample was Java Magazine’s worldwide subscriber base. Java Magazine supplied Erdos & Morgan with a list of 9,985 subscribers.

On February 2, 2017, an invite letter was e-mailed to all sample members explaining the research objectives and directing them to a special URL to complete the survey.

Reminder letters were e-mailed to non-responders on February 8th and February 16th.

The incentive to respond was a sweepstakes offer to win one (1) of five (5) Amazon.com gift certificates, value at $100.00 each.

A total of 271 e-mail addresses were eliminated, leaving a new effective e-mailing of 9,714. When the survey closed for tabulations on February 21, 2017, there were 1,083 usable responses which represented an 11.1% response rate to the net mailing.

Erdos & Morgan prepared percentages and other calculations herein in accordance with accepted research practice.
