Schools can end the contract at any time without any extra penalty being incurred. Most educational organizations have expressed opposition to the presence of TV commercials in a classroom. You can visit our web site and read resolutions opposing the concept and opposing specifically Channel One. When a commercial is shown to students under force of contract, the school becomes an endorser of the product being advertised. That is unethical.
Public schools are government schools.
When a public school requires children to watch a commercial, then the government is telling children what products they should be purchasing or what movies they should watch. This is not a legitimate role of government. Channel One takes up one hour a week. The content of this hour is not controlled by the local community. Indeed, the community, through their school board, had to agree to limit the number of times they could not show the program.
