Google’s Q4 results fell short in nearly all areas, marking the start of a challenging era for the internet giant. Despite YoY growth of 1% to $76.05B, revenue was below the projected $76.5B. Advertising revenue saw a decline, with YouTube ad revenue at $7.96B instead of the expected $8.25B, a YoY drop of nearly $700M in Google Search revenue, and over $800M YoY decrease in Google Network revenue.
