Telecom Animation Film
From Sega Retro
Notice for Verifying Credits
Okay, I can't believe I have to make note of this, but since the Telecom page officially exists now, I have to warn future editors ahead of time: always, always check the sources for anything involving this company! If it's from any popular database (TVTropes, Wikipedia, IMDb), treat it with a grain of salt.
A good chunk of Telecom information has been fabricated by one person, who's attributed innumerable unrelated companies and animators for this company for reasons that I've detailed here. Some of this erroneous information are still on some online databases like the ones I've mentioned, and since said databases often claim it's "uncredited", trying to check if it's true can be a nightmare.
Luckily, SEGA Retro keeps records of game credits via PDF slideshows so we can easily curb erroneous false credits like these, but if you see something that claims it's by this company but "uncredited", take great caution.
