Some IPG Publishers Also Go DRM-Free

I knew it was only a matter of time after Macmillian’s TOR and Forge imprints went DRM-Free. Now there’s news that more publishers are heading down the unencumbered road.
The IPG (Independent Publisher’s Group) and Amazon have worked out their differences, with publishers under the IPG umbrella now restored to purchasability over Amazon. Some of those publishers, though not all, have decided to distribute their titles without DRM.
It’s been a little over a month since the TOR/Forge announcement. How long until we hear more dominoes falling? Not long, I bet.
