What Markets are Being Disrupted by Groupon?

In researching Groupon’s IPO for the earlier post, I tried to think about which markets are being affected by Groupon. The biggest is almost certainly Yellow Pages ($26Bn worldwide) — but there’s also Online Local Advertising ($10Bn and growing) and Coupon Books (probably much smaller?).
Are there others I’ve missed?
