THE CONTENT QUALITY QUESTION

Nearly half of Gen Z and millennials say they prefer social media content over TV and movies. This is a shift in how people define quality. Traditional markers like big-name stars and high production value matter less as audiences seek relevance and connection with creators. Choosing content is now influenced by ease, attention span, and mental effort. The media industry risks falling behind if it clings to outdated ideas of what makes content valuable.

TRUMP'S PAUSE ON MOST TARIFFS RAISES MORE QUESTIONS THAN ANSWERS AMID AD BUSINESS UNCERTAINTY

Trump paused most planned tariffs for 90 days on non-retaliating countries, but kept a 10% tariff on most others and increased the tariff on Chinese goods to 125%. The entertainment industry may suffer from advertising pullbacks and risks tied to China, such as a ban on U.S. films or intellectual property issues. Companies like Disney could benefit if trade deals reduce recession fears. Small and medium businesses, including celebrity-backed product lines, face the biggest risks from ongoing tariff uncertainty.

HEAD OF INSTAGRAM REVEALS SECRETS TO GROWING IN 2025 (50 MINUTE VIDEO)

To grow on Instagram, focus on feed posts for visibility while recognizing that Stories and DMs are more for direct interactions. Share short, engaging videos instead of long-form content to align with Instagram's priorities. Hashtags are no longer a reliable tactic for increasing reach, so focus on quality and relevance instead. Engage with your audience around the time you post to drive more profile visits. Most algorithm changes are small, so major drops in reach are often tied to outside events.

AI CONTENT WORKS, BUT ONLY IF YOU DO THE WORK

AI can boost content volume and production speed, but without the right systems, it creates more complexity. To scale effectively, teams need well-defined workflows that go beyond one-off prompts, combining multiple tools, human checkpoints, and prompt iterations. Editorial QA is also essential to catch bland or inaccurate output, while strategy and analytics are needed to guide the whole process.

WHY YOU NEED A CUSTOM CONTEXT PROVIDER

"Naked" React Context providers can be bad for performance due to unnecessary re-renders. Using custom context providers, which hold state management logic within a dedicated component, improves separation of concerns and prevents unrelated components from re-rendering. This approach uses component composition to make sure only context consumers update when the context value changes.
