I come from a TV news background, and now work in reality TV. I'll echo that you've gotten excellent input.
In TV news on the producer side Type A personalities really thrive. It's a very deadline-driven environment with constant changes as breaking news, equipment failures or other curveballs come in to play. You may be asked to write for multiple newscasts plus repurpose your content for the digital side. A person who loves to write, is a strong decision maker and can maintain structure and order in the midst of chaos do well in this position.
A typical day for a show producer or AP (associate producer) would begin with "the morning meeting," although that meeting occurs at least three times a day. It might be 2am for the morning show, 8am for the afternoon shows and 1pm for the evening shows. At the meeting, you go through the news captured for that day, the news potential for that day, enterprise opportunities everyone brings to the meeting (PLEASE come to the meeting with your own ideas!) and then it's all assessed, assigned to field crews and shows, and then everybody splits off to go divide and conquer- the field crews go gather and the producers start writing and editing elements for their show. That would include in and out bumps and teases, social media, digital media, promotional elements, etc. Current events are your best friend, and loving them might be an indicator you'd do well in news.
I worked in the field and was always so amazed at the strength of our news producers, as they maintained stability and kept an entire show together with so many unpredictable moving parts. With all respect to my producer friends, bossy, domineering personalities do well her too. I lived in the chaos-constant change side of things, but even there the strong writing, ability to react quickly and make important decisions on the fly were critical.
To work as a reporter, you need mad people skills, be a quick, accurate and exceptional writer, a competitive spirit and be able to do your best work every day with little to no supervision. I recommend studying journalism, political science, law and healthcare to do well in that type of media. There are great workshops you can do outside of college to strengthen those skills as well- the NPPA, the Poynter Institute and online courses offer great insight into the industry. You might also consider interning in a newsroom just for the insiders' perspective and experience.
In reality TV, the production work is much more of a true production, just like some of the shows described above. Yes, even reality TV is heavily planned and scripted. You capture great natural moments, but that is not the basis of the show. You need to know production from top to bottom, much like news, to be a great team member and contribute your best work to the product.
For a show, the production meetings start a few months out to evaluate content and characters (for reality or doc-style.) The crews needs are planned, budgeted and hired. The production calendar begins to take shape. Characters or subjects are booked for their shoots and factored into the production calendar. Travel has to be planned- the show I work on is shot in Texas but based out of Cali, so the executive and supervising producers travel, many of us are local crew and the editors stay back in LA and footage is uploaded or couriered at each day's wrap.
Once in production, you can expect regular 12-14 hour days in many cases. The day begins with a production meeting to cover safety elements, any restrictions on set (we may be shooting on a controlled set, a public venue we've booked such as a stadium, or public plaza, on private property such as people's homes, or stores, restaurants, etc.) as well as crew assignments, equipment needs, radio assignments, etc.
I'd say regardless of what medium you're looking into, realize that on the production side, it's always an 8 or 10 hour day for an hour or two of product. You have to love the behind-the-scenes and what goes into making it, not just be captivated by what you seen on a large, small or handheld screen!
Good luck to you- I think you asked a really smart question.
