VR/AR, OTT and Social Media
7.1 Virtual Reality, Augmented Reality and Mixed Reality
Virtual Reality (VR)
VR is a fully immersive computer-generated 3D environment. The user wears a headset (HMD — Head-Mounted Display) that blocks the real world.
Key hardware: Meta Quest 3, Sony PlayStation VR2, Apple Vision Pro ($3,499, 2024), Valve Index.
VR requires high-resolution displays, low-latency head tracking (gyroscope, accelerometer), positional tracking (inside-out cameras), and 6DoF (Degrees of Freedom) for natural movement.
Augmented Reality (AR)
AR overlays digital information (text, images, 3D models) on the real world, viewed through a smartphone camera or AR glasses.
Examples:
- Pokémon Go (2016 — first mass-market AR app, 500 million downloads)
- Google Maps AR navigation
- IKEA Place (see furniture in your room)
- Snapchat AR filters
Hardware: Google Glass (enterprise 2.0), Microsoft HoloLens 2 (industrial), Apple Vision Pro (MR), Meta Ray-Ban glasses.
Mixed Reality (MR)
MR is where physical and digital objects coexist and interact in real time. Holographic elements are anchored to real space.
Applications of VR/AR:
| Domain | Application |
|---|---|
| Education | Virtual anatomy labs, historical site visits, distance learning (metaverse classrooms) |
| Healthcare | Surgical simulation and training; phobia treatment (VR exposure therapy); pain management |
| Military | Flight simulator training, combat simulation, maintenance training |
| Tourism | Virtual heritage site visits; hotels using AR for room information |
| Real estate | Virtual property tours |
| E-commerce | AR try-on (Warby Parker glasses, Amazon virtual try-on) |
| Manufacturing | AR-guided assembly (Boeing uses AR headsets for wiring aircraft, reducing time by 25%) |
7.2 OTT Platforms
OTT (Over-The-Top) refers to media services delivered directly to viewers via the Internet, bypassing traditional TV infrastructure (cable, satellite, DTH).
Global OTT landscape (2024):
| Platform | Parent Company | Subscribers | Type |
|---|---|---|---|
| Netflix | Netflix Inc. | 238 million | SVOD (Subscription) |
| Amazon Prime Video | Amazon | 200 million+ | Part of Prime |
| Disney+ Hotstar | Disney/Star | 160 million | SVOD |
| YouTube | 2.5 billion users | AVOD (Ad-supported) | |
| Jio Cinema | Reliance | 200 million+ | AVOD + SVOD |
India's OTT context:
- 45+ OTT platforms in India; ~100 million paying subscribers (2024)
- IPL 2023 on Jio Cinema: Free streaming; 32 million concurrent viewers (record for any live streaming event globally)
- Netflix India price (2024): Rs 149 (mobile-only) to Rs 649 (4K) — localised pricing
- Regulation (IT Rules 2021): OTT platforms must self-classify content (U, U/A 7+, U/A 13+, U/A 16+, A); maintain a 3-tier grievance redressal mechanism; keep records for 90 days; appoint a Grievance Officer and resident India representative
7.3 Social Media
Social media platforms by Monthly Active Users (MAU, 2024):
| Platform | MAU | Primary Use |
|---|---|---|
| 3.05 billion | Social networking, groups, marketplace | |
| YouTube | 2.5 billion | Video sharing, streaming |
| 2 billion | Messaging, groups | |
| 2 billion | Photo/video sharing, stories, reels | |
| TikTok | 1.5 billion | Short-form video |

| Telegram | 900 million | Messaging, channels |
India's social media statistics (2024):
- 500 million+ social media users
- WhatsApp India: 500 million+ users — world's largest WhatsApp market
- Instagram India: 360 million+ users
- India banned TikTok on June 29, 2020 (along with 58 other Chinese apps) citing national security and data privacy
Social media governance in India:
IT (Intermediary Guidelines) Rules 2021 — Social media intermediaries with > 5 million users ("significant social media intermediaries") must:
- Appoint a Chief Compliance Officer, Nodal Officer, Grievance Officer (all India residents)
- Publish monthly compliance reports
- Enable "traceability" of first originator of messages (WhatsApp end-to-end encryption controversy)
- Provide voluntary user verification ("blue tick")
Ministry of Electronics and IT (MeitY) is the nodal ministry for IT Act enforcement. The Supreme Court examined IT Rules 2021 — some provisions challenged on free speech grounds (2022–2023).
Concerns:
- Hate speech and misinformation (infodemic during COVID-19)
- Radicalisation and election manipulation (Cambridge Analytica/Facebook scandal — 87 million users' data harvested without consent, 2018)
- Mental health impacts (especially on teenagers)
- Cyberbullying
