At the Independent Magazine Advisory Group’s sixth annual meeting in Boulder, Colorado this week, Bob Sacks, president of Precision Media Group, offered six key properties for what a magazine is.

Tellingly, his were platform-neutral:

1.    It’s metered. It’s paginated. It has a beginning, middle and end.
2.    It’s edited, or curated.
3.    It’s designed.
4.    It’s date-stamped.
5.    It’s permanent. Once created, it can’t be changed.
6.    It’s periodic. It has a calendar or rhythm. It has a series of issues.

[EDITOR’S NOTE: The original dek in this story included the phrase "none ink-on-paper"; while not technically incorrect, "platform-neutral" is closer to what Mr. Sacks’ was describing here.]
