3 quizzes - (at least) 3 giveaways

Here's a little 3-part TV themes quiz. There are three quizzes with nine TV themes each to solve and there's a giveaway waiting for you after each part (additionally there might or might not be secret giveaways hidden in time and space).
In order to get to the second and third quiz you have to solve the first and second one respectively.

The first quiz is about new series (younger than 20 years, counting from their TV premiere)
The second quiz is about old series (20+ years)
The third quiz is about series of any age

The difficulty is supposed to rise from part to part, however because of the nature of this puzzle your mileage may vary (if you have watched all "hard" series but none of the "easy" ones f.ex.)

Rules and stuff:
The usual puzzle rules apply (violation will lead to you getting blacklisted for all of my giveaways and might get you banned as well):

• No sharing of links/answers/hints/etc. Not on this site and not anywhere else.
• Do not give hints to other users
• Follow this link to start the first quiz: link
• Don't reveal what games I'm giving away here (they are no bundle games; all relatively new releases)
• If you're stuck somehwere, (spoiler-free) feedback in this thread is appreciated - I might give additional hints later on if many people are stuck in the same place (so come back to the OP from time to time in that case)

General information and hints:

• All giveaways connected to this puzzle have a CV of $0.01
• Giveaways end on July 1st, 23:55 CEST
• Sorry, headphone users: I realised too late there are big differences in the volume level in some themes - be careful ;-)
• Correct answer is the English title of the respective series. I tried to add more than one spelling where needed, however I might have overlooked something: If your answer won't be accepted although you're sure you have the correct answer, go to imdb.com and copy&paste the original title there - that should do it in every case.
• I tried to choose mostly internationally well known series, so most of them are from the UK or the US.
• The hints on itstoohard are supposed to make it possible to solve the quiz without knowing the shows, so you can try again later when they're unlocked for you (make sure to enter at least one guess to start the countdown, though).
• Going one week into the future, with a nice tune on your lips, can make you see things clearer. And did those feet in ancient times...
• Don't take the headline of the second quiz too literally, the TV shows are not limited to the 80s.
