We tend to think that idolatry is an Old Testament phenomenon.
Long ago, unenlightened people made little figurines from wood or stone or they built altars in the woods or on mountaintops. To us, that's idolatry.
We think we're more sophisticated today, so idolatry isn't a big problem like it was in the Old Testament.
However, it's not that idolatry isn't as prevalent today as in the Old Testament. It's just that our idolatry manifests itself differently. It's more sophisticated like we presume to be.
