Over the next year, Roku predicts that 100% of the streaming audience will see ads. For growth marketers in 2026, CTV will remain an important “safe space” as AI creates widespread disruption in the search and social channels. Plus, easier access to self-serve CTV ad buying tools and targeting options will lead to a surge in locally-targeted streaming campaigns.
Read our guide to find out why growth marketers should make sure CTV is part of their 2026 media mix.
AI in Healthcare and Biotech
Healthcare saw remarkable AI-driven breakthroughs in 2025, alongside wider clinical adoption of AI tools. After years of promise, AI is tangibly improving medical practice and research. For example, the U.S. FDA approved a record number of AI-powered medical devices – by 2023 the FDA had cleared 220+ AI devices (up from just 6 in 2015)hai.stanford.edu, and that number only grew in 2024–25 as more AI diagnostics came to market.
These include AI systems that can read medical images (X-rays, MRIs) faster than radiologists, detect early signs of diseases, or even predict patient deterioration in ICU. In 2025, a notable study showed an AI analyzing chest X-rays could predict a person’s “biological age” and cardiac risks that doctors might misscrescendo.aicrescendo.ai – hinting at new preventative screening tools. Perhaps even more groundbreaking, AI is accelerating drug discovery and biomedical research.
This year, researchers used generative AI models to design new antibiotic molecules effective against drug-resistant bacterianews.mit.edu, a critical area given rising superbugs. Similarly, multiple AI-designed drug candidates entered clinical trials for diseases ranging from cancer to rare conditionscrescendo.ai. Pharmaceutical companies now routinely employ AI to sift huge chemical databases and propose new compounds in weeks rather than years.
Hospitals also benefited from AI assistants: large language models, fine-tuned on medical knowledge, began helping doctors with clinical decisions and answering patient questions (with oversight). For example, the general public gained access to medical chatbots (built on GPT-like models) that can explain lab results or suggest wellness tips – though concerns about accuracy persist. Global health saw AI contributions too: in developing countries, AI diagnostic apps on smartphones helped triage symptoms, and AI-powered prediction models improved epidemic forecasting and vaccine distribution.
While doctors emphasize that AI won’t replace human clinicians, 2025 proved that in medicine, AI is maturing from experimental to essential – saving time, augmenting decision-making, and even discovering new treatments that could save lives.
