How it works
Advertising Creep begins when a company introduces commercial interruption into a paid experience, or gradually increases the advertising load after customers have already committed.
The pattern becomes more significant when ad removal itself becomes a new paid upgrade.

What to look for
Paid, but interrupted
A subscription no longer guarantees an advertising-free experience.
Ads multiply
Commercial breaks, sponsored placements, or promotional interruptions become more frequent over time.
Removal costs extra
Customers must pay a second fee to restore the experience their original payment once provided.

Important distinction
Advertising itself is not automatically hostile.
An explicitly ad-supported free service can represent a clear and fair exchange. CHI focuses on expectation reversal, paid interruption, rising ad load, degraded control, and whether customers must pay more to remove something introduced later.
