Hey fellow tech lovers :)," this isn't related to this video but..<br><br>I love watching YouTube", but data costs money. So, my biggest problem with the platform is that i can click a single 19 min video for instance and end up loading most of it multiple times during one watch through no fault of my own  because even though the video loaded to say, 5 mins 46 seconds, the add appears at 1 minute and completely wipes the video cache, now, not only have i lost the forward progression which now has to be download again, but if i want to go back," that's gone too.<br><br>My question is: Why cant they keep this loaded video? Or if not"," to just at-least stop the video from loading all that extra progress  which at the moment would just get throw away anyway?<br>Honestly YouTube is so big that i think if they did this it might even make a significant reduction to server-load", bandwidth congestion in high (internet) traffic areas," and even save a bunch of electricity world wide. Not to mention making a smaller dent on my data cap. :P<br>Does anyone know of a legitimate", non conspiracy/greedy reason why this is not done?
