The International Committee on Taxonomy of Viruses (ICTV) authorizes and organizes the taxonomic classification of and the nomenclatures for viruses. The ICTV have developed a universal taxonomic-scheme for viruses, and means to describe, name, and classify every virus that affects living organisms. The members of the International Committee on Taxonomy of Viruses are considered expert virologists. The ICTV was formed from and is governed by the Virology Division of the International Union of Microbiological Societies. Detailed work, such as delimiting the boundaries of species within a family, typically is performed by study groups of experts in the families.

Ithaca College Television (ICTV) is Ithaca College's student television channel. Founded in 1958 as the first student-run cable television station, ICTV provides original, student-produced programming to approximately 26,000 households in Tompkins County, New York through Spectrum Cable. Additionally, ICTV offers a livestream of its programming on its website, ICTV.org, along with on-demand episodes from past and present shows.

ICTV is a privately held TV channel in Ukraine. Its coverage area allows it to be received by 56.6% of the Ukrainian population, making the channel the fourth in the nation in terms of coverage, and third by the viewers' ratings.

Virus classification is the process of naming viruses and placing them into a taxonomic system. Similar to the classification systems used for cellular organisms, virus classification is the subject of ongoing debate and proposals. This is mainly due to the pseudo-living nature of viruses, which is to say they are non-living particles with some chemical characteristics similar to those of life, or non-cellular life. As such, they do not fit neatly into the established biological classification system in place for cellular organisms.

Comovirinae is a subfamily of viruses in the order Picornavirales, in the family Secoviridae; its genera were formerly classified in the family Comoviridae. Plants serve as natural hosts. There are currently 56 species in this subfamily, divided among 3 genera.

Artichoke Italian latent virus is a virus that infects plants. It consists of two segments of positive-sense, single-stranded RNA enclosed in an icosahedral capsid. Artichoke Italian latent virus can infect a variety of flowering plants, causing discoloration and growth stunting.

Marnaviridae is a family of positive-stranded RNA viruses in the order Picornavirales. The first marnavirus that was isolated, and which is the type species for the family, infects a Microphyte: the toxic bloom-forming Raphidophyte, Heterosigma akashiwo. Algae therefore seem to serve as natural hosts. There is only one genus (Marnavirus) and one species in this family, the type species Heterosigma akashiwo RNA virus (HaRNAV).

Benyvirus is a genus of viruses, in the family Benyviridae. Plant serve as natural hosts. There are currently four species in this genus including the type species Beet necrotic yellow vein virus. Diseases associated with this genus include: BNYVV: rhizomania.

Ourmiavirus is a genus of viruses. Cucurbits, cherry, and cassava serve as natural hosts. There are currently three species in this genus including the type species Ourmia melon virus. Diseases associated with this genus include: ouMV: yellowing and chlorotic spot symptoms.

Picornavirales is an order of viruses with vertebrate, insect, algal or plant hosts. The name has a dual etymology. First, picorna- is an acronym for poliovirus, insensitivity to ether, coxsackievirus, orphan virus, rhinovirus, and ribonucleic acid. Secondly, pico-, meaning extremely small, combines with RNA to describe these very small RNA viruses.

Aspiviridae, formerly Ophioviridae is a family of viruses characterized by an elongated and highly filamentous and flexible nucleocapsid with helical symmetry. It is a monotypic taxon containing only one genus, Ophiovirus. Aspiviridae is also the only family in the order Serpentovirales, which in turn is the only order in the class Milneviricetes.

Gammaflexiviridae is a family of viruses in the order Tymovirales. Fungi serve as natural hosts. There are currently only one genus, Mycoflexivirus, and one species in this family: the type species Botrytis virus F.

Secoviridae is a family of viruses in the order Picornavirales. Plants serve as natural hosts. There are currently 81 species in this family, divided among 8 genera or not assigned to a genus.

Ampullaviridae is a family of viruses that infect archaea of the genus Acidianus. Only one genus in this family has been described, Ampullavirus, which contains one species, Acidianus bottle-shaped virus. The name of the family and genus is derived from the Latin word for bottle, ampulla, due to the virions having the shape of a bottle. The family was first described during an investigation of the microbial flora of hot springs in Italy.

Bacillarnavirus is a genus of viruses in the order Picornavirales. Marine diatoms serve as natural hosts. There are currently three species in this genus, including the type species Rhizosolenia setigera RNA virus 01.

Nairoviridae is a family of viruses in the order Bunyavirales. Its name derives from Nairobi sheep disease, caused by the member Nairobi sheep disease orthonairovirus.

Phenuiviridae is a virus family belonging to the order Bunyavirales established by ICTV in 2016. Ruminants, camels, humans, and mosquitoes are the known hosts of members of this negative-sense single-stranded RNA virus family. Of the four genera, Phlebovirus is the only genera that includes viruses that infect humans and are associated with known disease in humans.

Hantaviridae is a family of viruses in the order Bunyavirales. It is named for the Hantan River area in South Korea where an early outbreak of one of its species was observed.

Peribunyaviridae is a family of viruses in the order Bunyavirales. Its name partially derives from Bunyamwera, Uganda, where the founding species was first isolated.

Riboviria is the only realm of viruses circumscribed as of March 2019. It contains all RNA viruses and viroids. As such, it takes the first part of its name, ribo- from ribonucleic acid, or RNA.

In virology, realm is the highest taxonomic rank established by the International Committee on Taxonomy of Viruses (ICTV). The names of realms are terminated with the suffix -viria. A realm is divided into subrealms.
