1. Media services and the information society
An information society is a society where creating, sharing and using information is a big part of work and daily life. Media services are the roads of this society.
What they change
- Learning: lessons, videos and libraries are open to anyone with a phone.
- News and speed: events become known in minutes. Weather alerts and emergency notices save lives.
- Voice for everyone: ordinary people can share ideas, not only big newspapers.
- Services: booking tickets, paying bills and meeting a doctor online need media and messages.
- Culture: songs and stories reach other places and languages.
Risks
- False news spreads as fast as true news.
- Privacy loss when too much is shared.
- Too much screen time and comparing with others.
- Digital divide: people without a phone or internet are left behind.
- Bullying and misuse of pictures and words.
2. Media services and the information industry
The information industry is the set of businesses that make, store, send or sell information and the tools for it. Media services both belong to it and feed it.
Who works in it
- Creators: writers, video makers, musicians, teachers, voice artists.
- Builders: software developers, designers, data and security experts.
- Operators: network and server engineers, support staff.
- Sellers: advertisers, marketing and sales teams.
Money flows
- Users pay a subscription or watch ads.
- The service pays creators and the people who run it.
- Small shops reach customers through the service, and new businesses appear (for example, devices, internet providers, editing tools).
Because of this, a village shop can sell far away, and a student can earn by making lessons. But a few big services can also hold a lot of power over what people see, so laws on privacy and fair competition matter.
3. Using media services as a good citizen
- Check before you share: who made it, is it recent, does another trusted source say the same?
- Protect privacy: yours and other people's.
- Respect others: no bullying, no hate, no copying someone's work.
- Balance: set screen-time limits.
- Help close the gap: teach family members how to use services safely.
These simple habits cut the red tower of risk without losing the green tower of benefits.
Try it
At home: take one media service you know and draw two columns, "Helps" and "Harms". Write three items in each. Then write one jobs list: who works to keep this service running?
In the 3D: slide Reach from 0 to 10. Predict which towers will grow. Then press "Check before sharing" and see which tower changes.
Key formulas and definitions
- Cause → effect: more links → faster spread → more benefit AND more risk
- Information society: information is the main resource
- Information industry: create, store, send and sell information
- Check before you share: source, date, second source
Worked examples
1. A flood alert spreads in a town through a local app. Name one benefit and one risk of such fast spread.
Benefit: people reach safety quickly. Risk: a false alert would also spread just as quickly, so the source must be checked.
2. A video service hires 5 editors, 3 developers and 2 support staff. How many jobs are linked to this one service?
5 + 3 + 2 = 10 jobs, and more appear for creators and advertisers outside the company.
3. A rumour starts with 4 people. Each person tells 3 new people, once. How many people have heard it after that round (including the first 4)?
New people = 4 × 3 = 12. Total = 4 + 12 = 16 people. Each further round grows it more.
Common mistakes
- Saying media only does good, or only harm. Most effects have two sides.
- Believing a message is true because it came from a friend. Check the source.
- Thinking only big companies create jobs. Creators and small shops also earn.
- Forgetting people who have no phone or internet. Fairness means thinking of them too.
