the radio stations also adopted the kogo callsign . the broadcasting division of time life purchased kogo tv and its sister radio stations in 1962 . 5 6 this deal was reached after failed attempts to sell the properties to triangle publications 7 and united artists 8 among others ;

kcst claimed that an american television network should not be affiliated with a station located outside u.s. borders . at the time of the switch abc was still the third ranked network behind second rated nbc and perennial leader cbs . over the next several years however abc began to experience ratings growth in their primetime programming and rose to first place during 1975 76 finishing the year with ten programs in nielsen s top twenty . in san diego kcst tv experienced a carryover effect and also rose to first place locally knocking kgtv down to third behind cbs station kfmb tv channel 8 . 12 but abc was never happy with having been forced onto the uhf dial in san diego and the unprecedented success gave the network the impetus to actively upgrade its affiliate roster nationwide . despite having more than a year remaining in its current agreement with nbc kgtv announced it was joining abc in june 1976 . 13 after kcst tv now knsd signed with nbc 14 the switch between the two stations took place on june 27 1977 . 15 on october 3 2011 mcgraw hill announced it was selling its entire television station group including kgtv and azteca america affiliate kzsd lp to the cincinnati based e. w. scripps company for 212 million . 16 the deal was completed on december 30 2011 resulting in mcgraw hill s exit from broadcasting after 39 years . 17 due to their current scripps ownership the station regularly has to disclaim especially in its medical reporting that it has no ties to the local scripps health system a completely separate organization created in 1923 from a bequest from ellen browning scripps a sister to scripps founder e. w. scripps as scripps health personnel are regularly asked to comment on medical stories in the san diego area including by kgtv . digital television edit digital channels edit the station s digital channel is multiplexed channel video aspect psip short name programming 18 10.1 720p 16 9 kgtv dt main kgtv programming abc 10.2 480i 4 3 lwn laff 10.15 kzsd dt simulcast of kzsd lp analog to digital conversion edit kgtv shut down its analog signal over vhf channel 10 on february 17 2009 the original target date in which full power television stations in the united states were to transition from analog to digital broadcasts under federal mandate which was later pushed back to june 12 2009 . the station s digital signal relocated from its pre transition uhf channel 25 to vhf channel 10 . 19 20 programming edit syndicated programming on kgtv includes inside edition rachael ray right this minute and live with kelly and michael among others . news operation edit 10 news helicopter sky10 kgtv presently broadcasts 39 hours of locally produced newscasts each week with six hours on weekdays and 4 hours each on saturdays and sundays . in addition the station produces the sports highlight program sports xtra at 11 30 p.m. on saturday and sunday evenings . of note kgtv along with xetv knsd and kswb tv is one of four san diego television stations with a 4 p.m. newscast . entitled the now san diego kgtv s 4 p.m. newscast originally premiered under the title 10 4 in 2009 . kgtv first began to challenge the longstanding local news dominance of kfmb in the mid 1970s when anchors jack white and harold greene along with popular weather anchor captain mike ambrose and sportscasters al coupee and hal clement led the station s newscasts then simply titled the news to first place in the ratings albeit briefly . even with the brief return of greene following his stints in san francisco and los angeles the station fell back to second place behind kfmb in the early 1980s . however management succeeded in hiring away popular anchor michael tuck from kfmb in 1984 ; the move resulted in kgtv reclaiming first place and giving the station credibility by way of tuck s infamous nightly commentaries titled perspectives . kgtv also made history by being the first station in san diego with a female anchor team on its 11 00 p.m. newscast featuring carol lebeau and bree walker . after walker left in 1987 kimberly hunt would team with lebeau and form the city s longest running anchor duo at 15 years . during that time lebeau and hunt would anchor alongside tuck who left for los angeles in 1990 only to return to san diego on kfmb stephen clark now at sister station wxyz tv in detroit steve wolford and a returning hal clement who had switched from sports to news duties in 1983 while working at kfmb . eventually kgtv would decline after hunt left for an anchor position at kusi tv channel 51 alongside tuck ;
