I timed a couple of different channels and nothing is as bad as CNBC. ABC over the air was 33 seconds behind, MSNBC cable was only 15 seconds. (for comparison ABC over the air vs. cable is 8 seconds)
So I am guessing CNBC could be artificially delayed for business reasons. Like delayed quotes on a chart...
I sometimes watch my cable TV on my tablet or cell phone...no delays for any cable channel except for very popular events.
Therefore, I'm going to assume you're not talking about CNBC but instead are talking about the mobile CNBC
Pro product that is subscription base (extra fee) ?
They have a US live stream, Asia live stream and Europe live stream. I only used the CNBC Pro product in Europe and Asia while having access to regular CNBC. I didn't test the US live stream.
I didn't see any delays but I decided it wasn't worth it. I just wanted to test it out just in case I ended up in the hospital again but this time around I would have my tablet in comparison to not having access to anything the last time.
Yet, once around during peak times of like during big events...I did see a 1 - 2 second delay. I did the same test for regular Bloomberg TV on cable versus Bloomberg on tablet...no delays in US and Europe but the commercials were different...commercials on regular Bloomberg TV versus commercials on the mobile Bloomberg TV app (I believe its still free). Also, I didn't test Bloomberg TV on TV versus Bloomberg TV on a tablet. In contrast, I tested Bloomberg TV versus their mobile content. Both almost the same except for the commercials.
Thus, I'm not sure if you're testing CNBC regular cable versus a special CNBC mobile content like CNBC Pro
or if you're talking about CNBC regular cable versus the exact same cable content on your tablet for comparison side by side (tablet on a table next to a TV)...I suspect the latter because if you were talking about the mobile Pro content...you would have mentioned that.
On a side note...I did watch the superbowl on TV and watched it on tablet at the same time. There was about a 30 sec delay and the commercials were exactly the same. In contrast, a friend was watching the superbowl from his tablet and was subscribing to a mobile sports app...
He had different commercials than his regular TV and the mobile app was delayed by about 30 seconds along with the fact that during the game...the TV had different angles of the competition versus the mobile app. That told him that there was a different broadcast (live stream TV crew) by the same company versus their regular cable TV subscriber
