The Online Content Regulations, which were first introduced in 2018 and later replaced by the Online Content Regulations of 2020, require online content service providers to have an operating license. The license is applicable to providers who cover news, entertainment, educational, and religious content through blogs, social media pages, and similar services. Therefore, on top of traditional media websites, online TV and radio channels, individual bloggers and podcasters are required to have a license.
According to the regulations, a person can only provide content services after obtaining a license from the Tanzania Communications Regulatory Authority (TCRA). There are four categories of online content licenses available for providers of predominant news and current affairs: entertainment content, educational and religious content, and simulcasting. Upon successful application, the licensee is required to pay an initial fee of TZS 1,000,000 (USD 433 approx.) for a news and current affairs license, TZS 500,000 (USD 216 approx.) for an entertainment and education license or religious content license, and TZS 200,000 (USD 87 approx.) for a simulcasting license. The same fees apply for annual payments and license renewal, and the license is valid for three years. If a licensee breaches the terms and conditions of the license, the license may be suspended or revoked by the TCRA. The licensee is notified of the revocation or suspension and the reasons for it and must surrender the license to the TCRA within seven days after service of the revocation or suspension notice. In addition, the failure to adhere to these regulations makes the service provider liable to a fine of not less than five million shillings (equivalent to approx. 2,150 USD) or imprisonment for a term of not less than 12 months or both.
It is reported that content providers used to be able to register and get a single license to offer different types of content, but with the 2020 Regulations, they are required to obtain numerous permits based on the content they offer and can incur exorbitant licensing fees. In addition, it is reported that as a result of this licensing regime, some blogs were closed down.
