XHAB-TDT is the television call sign for the Televisa television station in Matamoros, Tamaulipas, Mexico. The channel can also be seen in Texas' Rio Grande Valley market. In addition to local news and programming, XHAB also airs a selection of Televisa's programming. XHAB also shares a sales office with XERV-TV in McAllen, Texas, for sales of commercial time from American businesses.
XHAB returned channel 7 to the air in Matamoros upon signing on in 1968; the channel had been occupied by XELD-TV in the early 1950s.
An interesting coincidence is between XHAB and the Univision affiliate KNVO; they both carry some of the same TV programming provided by Televisa (in XHAB's case, because it is a Televisa affiliate; in KNVO's case, Univision carries some Televisa programming in its lineup and this is thus reflected in KNVO's lineup).
