Metric: calculate MER by dividing total revenue by total marketing spend (e.g., $500k / $100k = 5.0). Analysis: use MER to catch when high-ROAS channels are just cannibalizing organic traffic. Action: build a blended MER dashboard to report holistic growth health to leadership.

Key signals: 'AI-ready' is the new standard for laptops (Intel Panther Lake, Snapdragon X2) and displays. Beyond PCs, expect dedicated 'agentic gadgets'—wearables and handhelds designed solely to house AI assistants—to challenge the smartphone status quo. LG and Samsung are pushing RGB LED and Micro RGB tech, while smart home devices (vacuums, locks) finally get useful AI interoperability via Matter. The era of the 'AI PC' is over; now it's just 'the PC'.

Key frameworks: 1) 'Synthetic Personas' that evolve with real-time data to test messaging before launch. 2) 'Campaign Down' approach for rapid asset generation. 3) Multi-channel orchestration that adjusts timing/frequency based on individual fatigue signals (reducing unsubscribes by 20-40%).
