The 2018 ACA (Affordable Care) enrollment period has been shortened from 90 days to 45 days (November 1-December 15, 2017) and the advertising budget to promote open enrollment has been slashed from $1M to $100k in an effort to sabotage the program. You're probably not seeing a lot of advertising (read: zero) about the enrollment window online or on TV.
