# Fullstory for Media & Entertainment

> ⚠️ **LEGAL DISCLAIMER**: This guidance is for educational purposes only and does not constitute legal, compliance, or regulatory advice. Media applications may be subject to various regulations (GDPR, CCPA, COPPA for children's content, accessibility requirements). Always consult with your legal and compliance teams before implementing any data capture solution. Your organization is responsible for ensuring compliance with all applicable regulations.

## Industry Overview

Media and entertainment have unique characteristics for session analytics:

- **Engagement focus**: Time spent, content consumed, completion rates
- **Subscription models**: Free vs. paid, trial conversions, churn prevention
- **Content discovery**: Recommendations, search, browsing patterns
- **Ad-supported models**: Ad viewability, skip rates, revenue optimization
- **Multi-device**: TV, mobile, web, tablet experiences
- **Personalization**: Recommendation effectiveness, preference learning

### Key Goals for Media Implementations

1. **Optimize subscription conversion** and reduce churn
2. **Understand content engagement** patterns
3. **Improve content discovery** and recommendations
4. **Reduce friction** in video playback experience
5. **Optimize paywall** placement and messaging
6. **Track cross-device** user journeys

## What Can Be Captured in Media

| Data Type | Capture? | Privacy Level | Notes |
|-----------|----------|---------------|-------|
| Content viewed (titles) | ✅ Yes | Unmask | Core analytics |
| Watch time / progress | ✅ Yes | Unmask | Engagement metrics |
| Search queries | ✅ Yes | Unmask | Content discovery |
| Browse behavior | ✅ Yes | Unmask | Recommendation analysis |
| Subscription plan | ✅ Yes | Unmask | Segmentation |
| User preferences | ✅ Yes | Unmask | Product data |
| Ratings/reviews | ⚠️ Consider | Mask if user visible | User-generated |
| User names | ⚠️ Mask | Mask | PII |
| Email | ⚠️ Consider | Hash/Mask | For identification |
| Payment details | ❌ Never | Exclude | PCI |
| Children's data | ❌ Never | Exclude | COPPA |

### Special Consideration: COPPA Compliance

If your platform serves children under 13:
- ❌ Do NOT use Fullstory on children's profiles
- ❌ Do NOT capture any data about children's viewing habits
- ✅ Only capture data for verified adult accounts

### Accessibility Feature Tracking

Media platforms must track accessibility feature usage to ensure compliance with WCAG/ADA requirements and improve experiences for all users:

| Accessibility Feature | Track? | Why |
|----------------------|--------|-----|
| **Closed captions/subtitles** | ✅ Yes | Engagement with CC content |
| **Audio descriptions** | ✅ Yes | Usage rates, content coverage |
| **Playback speed** | ✅ Yes | Accessibility and preference |
| **Screen reader compatibility** | ⚠️ Consider | May need special implementation |
| **Keyboard navigation** | ✅ Yes | Identifies non-mouse users |
| **Font size/contrast settings** | ✅ Yes | Accessibility preference adoption |
| **Disability status** | ❌ Never | Sensitive PII |

```javascript
// Track accessibility feature usage
FS('trackEvent', {
  name: 'accessibility_feature_enabled',
  properties: {
    feature: 'closed_captions',
    language: 'en',
    content_type: 'movie',
    content_id: 'mov_12345',
    first_time: true,   // Is this the first time this user enabled CC?
    // Helps identify accessibility feature adoption and content gaps
  }
});

// Track accessibility journey patterns
FS('setProperties', {
  type: 'user',
  properties: {
    uses_captions: true,
    uses_audio_descriptions: false,
    preferred_playback_speed: 1.0,
    // Never track WHY they use these features, only THAT they do
  }
});
```

> **Important**: Track accessibility feature usage to improve coverage and experience, but NEVER ask or infer why users need these features.

function onLogin(user) {
  // Check for children's profile - DO NOT track
  if (user.profile.isKids) {
    FS('shutdown');
    return;
  }
  
  FS('setIdentity', {

## News/Publishing Patterns

For news and publishing sites:

```javascript
// Article tracking
FS('setProperties', {
  type: 'page',
  properties: {
    page_type: 'article',
    article_id: article.id,
    article_title: article.title,
    article_category: article.category,
    article_author: article.author,
    publish_date: article.publishDate,
    word_count: article.wordCount,
    has_paywall: article.isPremium,
    is_premium_content: article.isPremium
  }
});

// Reading progress
function onReadingProgress(percent) {
  FS('trackEvent', {
    name: 'article_read_progress',
    properties: {
      article_id: article.id,
      progress_percent: percent,  // 25, 50, 75, 100
      read_time_seconds: readTime
    }
  });
}

// Metered paywall
function onArticleLimitReached() {
  FS('trackEvent', {
    name: 'article_limit_reached',
    properties: {
      articles_read_this_month: articlesRead,
      limit: articleLimit
    }
  });
}
```

## Ad-Supported Model Patterns

For ad-supported streaming/content:

```javascript
// Ad tracking (for your analytics, not ad tracking)
function onAdStart(ad) {
  FS('trackEvent', {
    name: 'ad_started',
    properties: {
      ad_position: ad.position,  // "pre_roll", "mid_roll", "post_roll"
      ad_duration_seconds: ad.duration,
      content_id: currentContent.id,
      content_timestamp: contentTimestamp,
      is_skippable: ad.skippable
    }
  });
}

function onAdSkipped(ad) {
  FS('trackEvent', {
    name: 'ad_skipped',
    properties: {
      ad_position: ad.position,
      seconds_watched_before_skip: watchedBeforeSkip,
      content_id: currentContent.id
    }
  });
}

function onAdCompleted(ad) {
  FS('trackEvent', {
    name: 'ad_completed',
    properties: {
      ad_position: ad.position,
      ad_duration_seconds: ad.duration,
      content_id: currentContent.id
    }
  });
}

// Upgrade prompt (for ad-supported to paid)
function onUpgradeToAdFreePrompt() {
  FS('trackEvent', {
    name: 'upgrade_prompt_shown',
    properties: {
      prompt_type: 'ad_free',
      trigger: 'ad_frequency',  // after X ads
      content_id: currentContent.id
    }
  });
}
```

## Churn Prevention Signals

```javascript
// Engagement signals for churn prediction
FS('setProperties', {
  type: 'user',
  properties: {
    // Activity metrics
    days_since_last_watch: daysSinceLastWatch,
    watch_frequency: getWatchFrequency(),  // "daily", "weekly", "monthly", "rare"
    hours_watched_7d: hoursWatched7d,
    hours_watched_30d: hoursWatched30d,
    
    // Content engagement
    titles_started_30d: titlesStarted,
    titles_completed_30d: titlesCompleted,
    completion_rate: titlesCompleted / titlesStarted,
    
    // Feature usage
    uses_downloads: hasDownloads,
    uses_profiles: profilesCount > 1,
    uses_my_list: myListCount > 0,
    
    // Subscription health
    payment_failures_90d: paymentFailures,
    contacted_support_30d: contactedSupport
  }
});

// Cancellation flow tracking
function onCancellationInitiated(reason) {
  FS('trackEvent', {
    name: 'cancellation_initiated',
    properties: {
      cancellation_reason: reason,  // "price", "not_using", "content", "switching"
      subscription_tenure_days: tenureDays,
      last_watch_days_ago: daysSinceLastWatch
    }
  });
}

function onCancellationCompleted() {
  FS('trackEvent', {
    name: 'cancellation_completed',
    properties: {
      save_offer_shown: saveOfferShown,
      save_offer_accepted: saveOfferAccepted
    }
  });
}

function onCancellationSaved(offer) {
  FS('trackEvent', {
    name: 'cancellation_saved',
    properties: {
      save_offer_type: offer.type,  // "discount", "pause", "downgrade"
      offer_value: offer.value
    }
  });
}
```

## KEY TAKEAWAYS FOR AGENT

When helping media clients with Fullstory:

1. **Content engagement is core**: Track views, progress, completions, interactions
2. **Subscription conversion is critical**: Track full funnel from browse to paid
3. **Video player interactions are valuable**: Skip, seek, quality, subtitles
4. **COPPA compliance**: Never track children's profiles
5. **Payment details excluded**: Standard PCI compliance
6. **Recommendations tracking**: Understand what drives content discovery

### Questions to Ask Media Clients

1. "Do you have children's profiles that need special handling?"
2. "Are you tracking video playback events comprehensively?"
3. "How are you measuring subscription conversion funnel?"
4. "Do you have ad-supported tiers to track?"
5. "How do you define 'engagement' for churn prediction?"

### Key Metrics to Track

- Browse-to-play conversion
- Content completion rates
- Time to first play (onboarding)
- Subscription conversion rate
- Trial-to-paid conversion
- Churn indicators (declining watch time)
- Recommendation effectiveness
