Idolatry is as real and present a danger for people today as it was for the people of the ancient world. Our present day idols are not just represented in statues but in currency, relationships, religion, pleasure, and possessions. Tim Keller, pastor of Redeemer Presbyterian Church in NYC preached an excellent message on this subject which I strongly encourage you to take the time and listen to.
