What type of content is limited to Media Mail?

Media Mail is a specific mail service offered by the United States Postal Service (USPS) that provides an economical way to send educational materials. The restrictions on what can be mailed via Media Mail are quite specific to promote its use for educational and informational items.

The correct choice focuses on the types of content specifically covered under Media Mail regulations, which include books, sound recordings, recorded video tapes, printed music, and recorded computer-readable media. These items are categorized as educational or informational and are eligible because they are primarily intended for the dissemination of knowledge. This eligibility helps to ensure that Media Mail remains an affordable option for sending such materials, thereby supporting education and information sharing.

The other choices do not meet the criteria set forth by the USPS for Media Mail. Clothing and accessories do not have educational value, electronic items do not fit the criteria of being primarily educational when they are not in the forms listed, and promotional materials are generally not considered to be informational content suited for Media Mail.
