I suppose the answer depends on what one means by 'reality' TV. If it means shows about dysfunctional celebrities, or folks performing ridiculous stunts, then probably and hopefully no.
If it means programs like PBS's NOVA, or back in the day, CBS's 21st Century (sponsored by Union Carbide, renamed from
The 20th Century), then perhaps some physics and science majors watch it.
In high school, I'd watch news or movies and do homework. On weekends, I spend a lot of time in either the city library or university library researching military history, pyrotechnics and high explosives, astrophysics, and plasma, nuclear and particle physics - and the occasional foray into political history, moral philosophy and religious studies - particular eastern religions.
In university, I was too busy to watch TV. In grad school, I would watch the news, and maybe programs like Dr. Who and Star Trek, otherwise, I was doing homework, research or at a full time job.
Professionally, my TV watching is spotty - mostly movies. Otherwise, I'm at PF or doing research.
