KTVT was also all over CBSN at times too
Upon hearing of the shooting while watching MSNBC, I immediately switched to local coverage, at first checking WFAA 8 (Only to find they weren't streaming) & then former Fox O&O KDFW 4 who still uses Livestream for streaming (Not that that means anything but worth mentioning given how many inroads NewsOn had made in such a short amount of time). I stuck with KDFW for most of the night (Smart move considering WFAA 8 was only streaming during its 10 PM news (Something WFAA would NEVER had done in 1963 when JFK was shot & assassinated if the Internet & today's media options were around then)
Not sure if WFAA went to JKL at 10:35 PM or not but if so, TEGNA might wanna look into this.....
