DRTV generally bypasses traditional retail stores to make a product sale directly with the consumer, but can also be used to drive product sales at retail. DRTV is comprised of three primary marketing subgroups of short form, long form and live home shopping.
Persia/Persian is more or less synonymous with Iran/Iranian. Persia is just the older name whereas Iran is the country's modern name. I think people from Iran call themselves Persian because of Iran's negative image in the west since the 1979 revolution.
Persian is a pluricentric language and its grammar is similar to that of many contemporary European languages. Persian is so-called due to its origin from the capital of the Achaemenid empire, Persis (Fars or Pars) hence the name Persian (Farsi or Parsi) .t is an Iranian language and as such, like its modern-day variant, a branch of the Indo-European language family. The oldest known text written in Old Persian is from the Behistun Inscriptions. Examples of Old Persian have been found in what is now present-day Iran, Turkey, Bahrain, Iraq, and Egypt.
