This document discusses the issue of advertising in schools. It outlines three main types of advertising: 1) Sponsored educational materials, 2) Direct advertising such as bus wraps and locker ads, and 3) Contests and incentives that offer prizes. It also discusses the Channel One program, which provides hardware to schools in exchange for airing commercials during daily 12 minute newscasts viewed by students. While advertising can generate revenue for cash-strapped schools, it exposes a captive student audience and risks blurring the line between education and commercial promotion.
