XHTV (channel 4 analog and channel 49 digital), founded in 1950 by Don Romulo O''Farril, is a flagship TV station of Televisa. Known in Spanish as Canal de la Ciudad (The City''s Channel in English), this station primarily targets the Mexico City metro area and thus a lot of the programming reflects life in Mexico City. For this reason, this station only has very few satellites and translators outside Mexico City (unlike its sisters), although its available nationwide on the SKY satellite service and selected cable systems; some of its programs can be seen on Televisa''s local stations across Mexico. A television station is a type of broadcast station that broadcasts video and usually audio to television receivers in a particular area. Traditionally, TV stations made their broadcasts by sending specially-encoded radio signals over the air, called terrestrial television.
