I wanted a blurry logo on an old TV screen. The process of getting there was kinda fun:
Started out with a simple logo:
First I uploaded the logo to https://photomosh.com/ where you can create GIFs with awesome effects.
I used Bad TV and RGB Shift
Output:
Next, I search on Turbosquid to find a suitable TV set. Found the one from the Videotextures Tutorial and went with it

Following the Video Textures Tutorial I attached the videotextures script and set the ScreenMirror Material of the model as the target texture.
Since this approach does not work with GIFs I searched the Forums and found @will 's GIF to MP4 Conversion suggestion. Works like a charm.
The only downside was a chrome error since there isn’t any audio track included:
Found a suitable tv noise sound effect on www.soundjay.com.
You can add an audio track to an MP4 file with a nifty tool called MP4Box:
MP4Box -add tv-static-01.mp3 myvid.mp4
Slight adjustments to the tiling of the vidtexture:
And added an outward-facing spotlight.
And that was basically it
