In the United States, net neutrality—the principle that Internet service providers (ISPs) should make no distinctions between different kinds of content on the Internet, and to not discriminate based on such distinctions—has been an issue of contention between end-users and ISPs since the 1990s. With net neutrality, ISPs may not intentionally block, slow down, or charge different rates for specific online content. Without net neutrality, ISPs may prioritize certain types of traffic, meter others, or potentially block specific types of content, while charging consumers different rates for that content.
Users with faster Internet connectivity (e.g., fiber) abandon a slow-loading video at a faster rate than users with slower Internet connectivity (e.g., cable or mobile). A "fast lane" in the Internet can irrevocably decrease the user's tolerance to the relative slowness of the "slow lane".
